3. Figure 2
Forest plot showing a significant treatment effect of CPAP on endothelial function, assessed by FMD of the brachial artery, compared with standard care. There was no significant treatment effect of CPAP on arterial stiffness, assessed by augmentation index, compared with standard care. See Figure 1 legend for expansion of abbreviation.
