From: Lack of reproducibility of trial sequential analyses: a meta-epidemiological study
The pie charts of studies with different reproducible levels A for groups A, B, C, and D and B for groups E and F. Group A: TSAs that did not provide essential data to reproduce RIS; group B: TSAs that provided essential information to reproduce RIS; group C: TSAs that did not provide essential data to reproduce decision boundaries and Z-curves; group D: TSAs that provided essential data to reproduce decision boundaries and Z-curves; group E: non-reproducible TSAs; group F: reproducible TSAs
