Meta-analysis of 6-minute walk distance (6MWD). A demonstrates the changes of Δ6MWD after 12weeks of exercise training in controlled studies. B shows the changes of 6MWD stratified by follow-up time after 3weeks and the longer short-term (12, or 15weeks) of exercise training in uncontrolled studies. CI=confidence interval(s); IV=inverse variance; SD=Standard Deviation.

3. Fig. 2
Meta-analysis of parameters in cardiopulmonary exercise testing stratified by follow-up time after 3weeks and the longer short-term (10, 12, or 15weeks) of exercise training in included studies. A demonstrates the changes of peak VO2 per kg after exercise training. B shows the changes of maximal workload. C shows the changes of VO2 at AT. D demonstrates the changes of HR rest. CI=confidence interval(s); IV=inverse variance; SD=Standard Deviation.
