BACKGROUND: The association between the quality of evidence in systematic reviews
and authors' conclusions regarding the effectiveness of interventions relevant to
anaesthesia has not been examined. OBJECTIVE: The objectives of this study were:
to determine the proportion of systematic reviews in which the authors made a
conclusive statement about the effect of an intervention; to describe the quality
of evidence derived from outcomes in reviews that used the Grades of
Recommendation, Assessment, Development and Evaluation (GRADE) working group
system for grading the quality of evidence; and to identify review
characteristics associated with conclusiveness. DESIGN: Cross-sectional analysis
of Cochrane systematic reviews from the Anaesthesia, Critical Care and Emergency
Review Group was undertaken. DATA SOURCES: The Cochrane webpage was used to
identify reviews for inclusion (http://.ace.cochrane.org/). ELIGIBILITY CRITERIA:
New and updated versions of systematic reviews published up to 17 September 2015
were eligible. Protocols for systematic reviews were excluded. RESULTS: A total
of 159 reviews were included. GRADE was used in 103 reviews (65%). Of these,
high-level evidence for the primary outcome was identified in 11 reviews (10%).
The main reasons that quality of evidence for the primary outcome was downgraded
were risk of bias (n?=?44; 43%) and imprecision (n?=?36; 35%). Authors of 47%
(n?=?75) of the total number of reviews made conclusive statements about the
effects of interventions. Independent predictors of conclusiveness in the
subgroup of reviews with GRADE assessments were quality of evidence for the
primary outcome (odds ratio 2.03; 95% confidence interval: [1.18 to 3.52] and an
increasing number of studies included in reviews (OR 1.05; 95% CI: [1.01 to
1.09]). CONCLUSION: It was common for conclusive statements to be made about the
effects of interventions despite evidence for the primary outcome being rated
less than high quality. Improving methodological quality of trials would have the
greatest impact on improving the quality of evidence.
