Table 1.
Overview of 44 studies included in the systematic review by study characteristics.
Fig 1.
The plot shows the included estimates sorted by precision, along with their weights in the pooled effect estimate.
Fig 2.
The plot shows point estimates and 95% confidence intervals for different subsamples of studies, with a grey circle indicating the number of studies in each subsample.

Subsample analyses.
Fig 3.
The plot shows point estimates and 95% confidence intervals for different subsamples of studies, with a grey circle indicating the number of studies in each subsample.
Fig 4.
Differences across study level covariates.
The plot shows average estimates and 95% credibility intervals for different study level covariates. The parameters are constrained to sum to zero within each category (e.g., for each draw from the posterior distribution, the sum of country parameters will sum to zero, as will the sum of the period parameters, etc.) See S2 File for model details.
Fig 5.
Differences across case and control outcome combinations.
The plot shows average estimates and 95% credibility intervals for all combinations of case and control outcomes observed in the data. See S2 File for model details.
