Figure 4. Forest plot of pre vs. post test comparisons on Wmap within epo treatments. The plot includes comparisons of studies with and without control / placebo treatments, which measured submaximal as well as maximal performances in moderate hypoxia and normoxia conditions (N = 10 strata, see Panel B in Table 1). The size of the solid black squares represents the weight that the corresponding study exerts in the meta-analysis. Confidence intervals of estimates are displayed as a horizontal line through the black square. The unfilled diamond presents the pooled estimate
