This process provides
clinicians with the tools to
interpret the quality of studies
and determine the applicability
of the synthesis of multiple
studies' results to their
patients.
The validity of a study refers
to whether the results of the
study were obtained via sound
scientific methods. Bias
(defined as the systematic
deviation from the truth) and/or
confounding variables may
compromise the validity of the
finding. The reliability of the
study finds were determined
by the size of the intervention's
effect (the effect size) and how
precisely that effect was
estimated. This part of critical
appraisal examined the
numerical data reported in the
results section of a study.
When critically appraising the
the usefulness of a study for
clinical decision making, a
basic aspect of applicability is
to evaluate the study patients
in comparison with the patients
to whom the evidence would
be applied.
