From: The effects of environmental hypoxia on substrate utilisation during exercise: a meta-analysis
Forest plot of mean differences (means ± 95% CI) for studies investigating the effects of hypoxia on RER during exercise matched for relative intensities. The size of the circle represents the relative weight of the trial. CIs are represented by a horizontal line through their representative circles. The diamond quantifies the overall mean difference (means ± 95% CI). A, B, C and D refer to the different trial arms of each study. Details of which are provided in Table 1
