Forest plot for 6MWT: CR plus RT vs. CR. (MD = 63.98, 95% CI = 35.50 to 92.45, P < 0.001, I.2 = 99%, 7 RCT, n = 446). Note: alone RT vs. CR: experimental group= rehabilitation robot; control group= conventional rehabilitation. CR plus RT vs. CR: experimental group= CR+rehabilitation robot; control group=conventional rehabilitation
