The estimated overall log odds ratios (95% CrI) of the 8 risk factors in the pterygium data obtained by Model H (accounting for both between- and within-study correlations), Model M0 (only accounting for between-study correlations), and Model U (univariate model ignoring both between- and within-study correlations) using the Bayesian method.
