Comparison of Estimates between Cohort and Case–Control Studies in Meta-Analyses of Therapeutic Interventions: A Meta-Epidemiological Study
Fig 3
Sensitivity analysis of differences in effect estimates between case–control and cohort studies with available data on adjusted estimates.
Difference in treatment effect estimates is expressed as ratio of estimates (RE). A RE < 1 indicates that case–control studies yielded larger estimates of the intervention effect or adverse events than cohort studies.
