3. Fig 2
Forest plots of morphine consumption for: (a) 12–24 h interval; (b) 24–48 h interval. The sample size, mean, sds, and the pooled estimates of the mean difference are shown. The 95% CIs are shown as lines for individual studies and as diamonds for pooled estimates.

Forest plots depicting alternative subgrouping of the primary outcome (12–24 h interval morphine consumption) according to: (a) pregnancy; (b) use of intrathecal morphine. The sample size, mean, sds, and the pooled estimates of the mean difference are shown. The 95% CIs are shown as lines for individual studies and as diamonds for pooled estimates.
