3.4.2. FEF25-75%
7 studies [19,21-24,36,37] were included in the analysis and three
comparisons with the control group (Fig .5a). Compared with conventional
treatment, endurance and respiratory training [WMD=11.31, 95% CI
(2.13,20.48)], endurance training [WMD=0.74, 95% CI (-4.11,
5.58)], respiratory and strength training [WMD=1.29, 95% CI
(-13.39,15.97)]. After combined analysis, FEF25-75% [WMD=4.07, 95%
CI (-0.62, 8.77)], the difference was not statistically significant
(Fig. 5b).
