did not detect a statistical significant increase using the Mantel-Haenszel fixed-effects model with absolute risk differences as an effect measure, although their findings approached significance (p = 0.11). 1 In contrast, Tzellos et al. detected a statistically significant increase in cardiovascular risk using the Peto method (p = 0.04), which excluded studies with zero events. 2 An astute reader may wonder how there could be divergent results between these two meta-analyses which essentially use the same data.
