‘REML’ indicates that REML has been used (top half of the table) and ‘MM’ indicates that the method of moments has been used. The parameters µi are the log hazard ratios corresponding to the effects shown in Table II and ρ denotes the common assumed within-study correlation. Standard errors of estimates are in parentheses and the estimated between-study standard deviations are shown in square brackets. Max LL denotes the maximum log-likelihood obtained using the within-study correlations shown in a multivariate meta-analysis.
