Introduction
Helping you teach, learn
and practise evidence-based
medicine
Clinical Evidence brings you the best available evidence for a wide
range of conditions, and provides you with the necessary evidencebased medicine (EBM) skills and tools to make effective use of
published research, and to improve clinical practice and patient
outcomes.
Following the rigorous, gold-standard Clinical Evidence methodology,
we systematically find, assess and summarise the most relevant
evidence for a wide range of common clinical questions, and display
systematic review findings in a quick- and easy-to-use format.
We continuously develop and improve the Clinical Evidence website,
to ensure that we provide the best possible knowledge resources for
your EBM needs. Based on extensive customer feedback, we have
recently added numerous extra tools designed specifically to enhance
the teaching, learning and practice of EBM – including guidance on
designing literature searches, appraising evidence, calculating and
assessing risk, and explaining EBM to patients.
This user guide introduces you to the essential features of Clinical
Evidence, and will help you get the most out of them.
We very much welcome all your feedback. Please send us your
thoughts and ideas via the ‘Feedback’ button on every page, or by
emailing us at support@bmjgroup.com. We look forward to hearing
from you.

Navigating around a review

Clinical Evidence presents the information with a tabbed
sub-menu. This evidence has been selected by systematic
and rigorous searching to answer clinical questions while
focusing on outcomes that matter most to patients
and clinicians. Each treatment or intervention is then
categorised according to its benefits and harms.
The core evidence is supplemented by links, references, and
additional information.

Unique to Clinical Evidence: overview of effectiveness
The Clinical Evidence team regularly
assess the available evidence for a
range of conditions, with a focus on
clinical questions most frequently
asked by practitioners. Interventions
related to each question are
summarised in a table and categorised
by efficacy for most patients, with
icons for easy reference. Click the
description of each intervention to
access a summary, details of the
associated benefits and harms, and a
commentary.
EFFECTIVENESS CATEGORIES
Beneficial
For which effectiveness has been demonstrated by clear
evidence from systematic reviews, RCTs, or the best alternative
source of information, and for which expectation of harms is
small compared with the benefits.
Likely to be beneficial
For which effectiveness is less well established than those listed
under “beneficial”.
Trade-off between benefits and harms
For which clinicians should weigh up the beneficial and harmful
effects according to individual circumstances and priorities.
Unknown effectiveness
For which there are currently insufficient data or data of
inadequate quality.
Unlikely to be beneficial
For which lack of effectiveness is less well established than
those listed under “likely to be ineffective or harmful”.
Likely to be ineffective or harmful
For which ineffectiveness or associated harm has been
demonstrated by clear evidence.

interventions. It provides a succinct account of the current state
of evidence on the prevention and treatment of a wide range of
