Cochrane Handbook for Systematic Reviews of Interventions
Julian P T Higgins,Sally Green +1 more
TL;DR: The Cochrane Handbook for Systematic Reviews of Interventions is the official document that describes in detail the process of preparing and maintaining Cochrane systematic reviews on the effects of healthcare interventions.
Journal ArticleDOI
De testimonio: on the evidence for decisions about the use of therapeutic interventions.
TL;DR: Decisions about the use of therapeutic interventions, whether for individuals or entire healthcare systems, should be based on the totality of the available evidence, which means decision makers need to exercise judgement about whether evidence gathered from experimental or observational sources is fit for purpose.

The effectiveness and cost effectiveness of a national lay-led self care support programme for patients with long-term conditions: a pragmatic randomised controlled trial
Anne Kennedy,David Reeves,Peter Bower,Victoria Lee,Elizabeth Middleton,Gerry Richardson,Caroline Gardner,Claire Gately,Anne Rogers +8 more
TL;DR: Lay-led self care support groups are effective in improving self-efficacy and energy levels among patients with long-term conditions, and are likely to be cost effective over 6 months at conventional values of a decision-maker’s willingness to pay.

Journal ArticleDOI
Randomized, controlled trials, observational studies, and the hierarchy of research designs.
TL;DR: The results of well-designed observational studies (with either a cohort or a case-control design) do not systematically overestimate the magnitude of the effects of treatment as compared with those in randomized, controlled trials on the same topic.
Journal ArticleDOI
A comparison of observational studies and randomized, controlled trials.
Kjell Benson,Arthur J. Hartz +1 more
TL;DR: Little evidence is found that estimates of treatment effects in observational studies reported after 1984 are either consistently larger than or qualitatively different from those obtained in randomized, controlled trials.
Journal ArticleDOI
A simple method for converting an odds ratio to effect size for use in meta-analysis.
TL;DR: It is shown that a ln(odds ratio) can be converted to effect size by dividing by 1.81, and the validity of effect size, the estimate of interest divided by the residual standard deviation, depends on comparable variation across studies.
