URRUTI is Spanish sample only but gives data for cigarettes per day. Study DEMEER based on Dutch sample only but rejected as unexposed group unsatisfactory. DEMARC Subsidiary p EKBERG Principal p Study EKBERG includes persons attending screening in Malmo and born approx 1913-65, so may overlap with NIHLEN (random sample of persons living in Malmo area and born approx 1933-72) and with STROM (50% of all men living in Malmo and born 1914) MONTNE Principal p Study MONTNE includes a random sample of persons living in Malmo area and born approx 1933-72, so may overlap with EKBERG (persons attending screening in Malmo and born approx 1913-65). Disease-free subjects from this study were followed up in study NIHLEN NIHLEN Principal i Study NIHLEN includes a random sample of persons living in Malmo area and born approx 1933-72, so may overlap with EKBERG (persons attending screening in Malmo and born approx 1913-65). NIHLEN is a follow-up of the disease-free subjects from study MONTNE. STROM Principal p Study STROM includes 50% of all men living in Malmo and born 1914, so may overlap with EKBERG (persons attending screening in Malmo and born approx 1913-65) ENRIGH Principal p p HOZAWA was conducted in 1987-89 in four communities, including Washington county MD and Forsyth County NC. ENRIGH also included those two counties but as it started in 1989 and included only age 65+ any overlap will be minimal. HARIKK was conducted in Washington/ Baltimore MD and continuously recruited subjects since 1958 HARIKK Principal i HOZAWA Principal p p FERRIS Principal p Study FERRI1 consists of original sample surveyed in 1961. Study FERRI2 is follow-up survey in 1967 which also included newly recruited second sample. Study FERRI3 is further follow-up cross-sectional survey in 1973. Study FERRI2 chosen as principal because based on largest sample. FERRIS Subsidiary p p FERRIS Subsidiary p GODTFR Principal i Study GODTFR is pooled analysis of 3 prospective studies, with outcome COPD hospitalization and excluding subjects with previous hospitalization. Study VESTBO is baseline prevalence of GOLD-COPD in the Copenhagen City Heart Study, SUADIC is cross-sectional analysis of MRC-CB at 15-year follow-up in the Copenhagen Male Study, and HOLLNA is baseline prevalence of CB in the Glostrup Study. All have been marked as principal although some overlap with GODTFR is likely. Study LANGE is follow-up to COPD-related mortality from the CCHS this is marked as subsidiary to GODTFR, and some overlap with VESTBO is likely. LANGE2 is a cross-sectional analysis of CB at 15year follow-up in the CCHS - this is marked as subsidiary to VESTBO, and some overlap with GODTFR is likely GODTFR Subsidiary m HOLLNA Principal p SUADIC Principal p VESTBO Principal p VESTBO Subsidiary p HAMMO2 Principal m m HAMMO2 is based in 25 states, ENSTRO is based on subset of subjects in one state only but follow-up is longer HAMMO2 Subsidiary m HARDIE Principal p p p Half of subjects in study BROGGE were drawn from survivors of study JOHANN (ongoing community cohort study up to age 82 in county Hordaland incl Bergen since 1985) and the remainder from hospital records in Bergen.

Study KAHN2 is based on only 8.5 years follow-up but gives detailed results for CB and EM KAHN Subsidiary m m m KOTAN1 Principal p Study KOTAN1 was a postal cross-sectional survey. Study KOTAN2 comprises a random subsample from part of the study area invited to clinical study KOTAN1 Subsidiary p KRZYZA Principal i Study SAWICK is baseline analysis using outcomes FEV1/FVC <60% and MRC-CB. Follow-up study KRZYZA excludes subjects with baseline FEV1/FVC <70% (so no overlap with SAWICK) but analyses outcome FEV1/FVC <65% at 13 years. Results entered as study WOJTYN defines outcomes as FEV1/FVC<70% and MRC-CB both at baseline and at 5-year follow-up, and is marked as subsidiary study SAWICK Principal p p SAWICK Subsidiary p p LAM2 Principal p Study LAM3 is prospective follow-up of disease-free subjects from LAM2 LAM3 Principal m LEBOWI Principal p p p Study LEBOWI is baseline study of subjects who were prospectively followed-up in study SILVA. As the outcomes studied are not identical, some cases may be included in both studies. Results from paper LEBOWI1977 omitted due to considerable inconsistencies in data presented SILVA Principal i i i LINDBE Principal i Study LUNDB2 was the first wave (1986) of the OLIN study, analysed as CC with a subset of symptom-free subjects as controls for CB cases. The full cohort but males only was also analysed cross-sectionally (data not entered but mentioned as alternative CB outcome in LUNDB2), and also served as a control group in a study of miners (study HEDLUN, subsequently rejected). A subset of the original full cohort was contacted again in 1996 and analysed for both prevalent COPD (study LUNDB1) and subsequent incidence (study LINDBE). LUNDB2 is marked as subsidiary to LUNDB1 LUNDBA Principal p LUNDBA Subsidiary p MANNI2 Principal p Study MANNI2 is baseline prevalence, MANNI3 is follow-up of COPDfree subjects MANNI3 Principal m MARAN1 Principal p Study MARAN1 includes prevalence at baseline and study MARAN2 includes incidence in 1 year follow-up of those disease-free at baseline MARAN2 Principal i OSWAL2 Principal p 36% of cases in CC study OSWAL1 were civil servants, and some overlap with OSWAL2, a cross-sectional study in civil servants, cannot be ruled out OSWALD Principal p PETO Principal m Study PETO includes 5 samples, one of which is also reported as a subsidiary study (HIGGI2) PETO Subsidiary p TAGER Principal p Study TAGER refers to 1st degree relatives and is based on a random sample of subjects aged 45-54 years while study TAGER2 refers to cluster sample of households and includes subjects aged 5+ years TAGER2 Principal p - -9- Na 25 TypebREF C TANG 25 25 26 C HAWTHO C WALD C TODD 26 27 C LAMBER C VINEIS 27 27 28 C KARAKA C SARGEA C VOLLM2 28 29 C VOLLM1 C WEN 29 30 C LIAW B WILSO1 30 B WILSO2 REFGPb Princ/Subsidb COPDc CBc Empc Comment TANG Principal m Study TANG is marked as principal study and is a pooled analysis of 4 samples, 2 of which are also entered as subsidiaries. Study HAWTHO includes 3 samples one of which (survey 3) was drawn from Paisley in 1974-5 thus also included in TANG (Renfrew and Paisley 1972-76). Study WALD (the BUPA study) is also included in the TANG analysis. TANG Subsidiary m p TANG Subsidiary m TODD Principal m Study LAMBER is baseline study of prevalent CB. Study TODD is 12year follow-up of CNSLD mortality (not excluding subjects with baseline CB) TODD Subsidiary p VINEIS Principal m VINEIS is the multi-national EPIC study, conducted in 10 countries and is marked as principal. SARGEA (UK) and KARAKA (Greece) were analyses using the data from one country only and are marked as subsidiary VINEIS Subsidiary p VINEIS Subsidiary p VOLLME Principal m Study VOLLM1 is baseline, and VOLLM2 is prospective follow-up of all subjects VOLLME Subsidiary p WEN Principal m m m Study WEN includes two cohorts (community and civil service/teachers) followed until 2000, with results available only for males. Study LIAW reports both sexes for the community cohort only, with follow-up to 1993, and is marked as subsidiary WEN Subsidiary m WILSO1 Principal p WILSO1 was conducted in northwest Adelaide among persons age 18+ in 2000, WILSO2 in metropolitan Adelaide and country towns among persons age 15+ in 1998, so some overlap cannot be ruled out WILSO2 Principal p p a N identifies linked studies (the numbering is based on alphabetical order of the first principal study in each set). b If the studies are independent (Type A), or the overlap between studies is deemed minor (Type B), then each study is marked as principal and has a separate value of REFGP. Where the overlap is deemed major (Type C), the studies share a common value of REFGP, and only one study within REFGP is marked as principal. The principal study is chosen on the basis of factors such as largest study size, widest geographical coverage or longest follow-up, and not on assessment of study quality. A/B indicates a type A link with at least one study in the set and a type B with another, and similarly for A/C and B/C – see Comment for details. c Availability of each outcome is indicated by m=mortality, i=incidence and p=prevalence -10- Table 3 Study characteristics All studiesa Variablec Levelsc Total CC Prosp 20 39 Study Typeb CrossSec Subsid Total 134 25 218 Study type case/control prospective cross-sectional nested case/control 20 0 0 0 0 39 0 0 0 0 134 0 2 8 14 1 22 47 148 1 Study sex both male female 17 2 1 20 17 2 108 23 3 20 5 0 165 47 6 Lowest age in study no limit <15 15 or adult NOS 16-19 20-29 30-39 40-49 50-59 60-69 70+ 4 0 1 0 3 6 5 0 1 0 0 1 0 3 10 15 7 0 3 0 5 4 21 12 32 11 29 8 8 4 0 0 2 1 9 6 5 1 1 0 9 5 24 16 54 38 46 9 13 4 Highest age in study (at baseline for prospective study) unknown 0 0 1 0 1 0 0 2 4 2 0 12 2 4 9 6 1 2 15 6 8 29 19 5 4 62 1 1 5 8 2 1 7 9 13 45 37 10 7 96 60-69 -

It is stated that CB/EM diagnosis was in last year, but it seems more likely that this means ever-diagnosed and disease active in last year. Results used refer to CB/EM versus all others. However no information is available on subjects with a history of inactive respiratory disease (diagnosis but no symptoms in last year, 68 subjects) or with childhood asthma (diagnosed before age 18, 18 subjects) so those subjects are omitted.
