Comparison of CIMBAL with complete case meta-analysis approach and gold standard (oracle) approach across different simulated data scenarios. The log-odds estimate of the exposure-outcome association (β^=log(OR^)) and its SE se^=Var^(β^) from the combined cohort over 2500 independent replicate datasets are plotted for each scenario: (1) fewer cohorts or (2) equal number of cohorts or (3) more cohorts with no confounder information than with complete confounder information. The horizontal dashed line in the β^-plots correspond to the true β=0
