## Figure 3.
Forest plots of placebo-controlled randomized trials examining the pooled effects
of statins on testosterone for men (top panel), women (middle panel) and both sexes
(bottom panel). In Kazerooni et al. [32], the reported SD was much smaller than in other trials, whereas the reported SD multiplied
by the square root of the sample size was similar to the SDs reported in other trials.
If we were to assume that the reported SD was actually the standard error, the pooled
estimate for women would be -0.40 nmol/l (95% CI -0.83 to 0.03) and the overall pooled
estimate would be -0.44 nmol/l (95% CI -0.80 to -0.08). Mean = mean difference; SD
= standard deviation.
