Results section, sentence 2: In the sentence beginning ‘Pairwise meta-analysis...’, the value ‘I2 = 92.4%’ should have read ‘I2 = 92.46%’. Results section, sentence 3: In the sentence beginning ‘Exercise training...’, the text ‘controls (g [95% CI]: 1.02 [0.67, 1.36], P < 0.001, I2 = 92.99%, studies: n = 42), usual-care controls (g [95% CI]: 0.65 [0.41, 0.89], P < 0.001, I2 = 84.82%, studies: n = 33)’ should have read ‘(g [95% CI]: 0.99 [0.66, 1.32], P < 0.001, I2 = 92.43%, studies: n = 42), usual care controls (g [95% CI]: 0.64 [0.44, 0.83], P < 0.001, I2 = 76.52%, studies: n = 33)’ and when all controls combined (g [95% CI]: 0.86 [0.64, 1.07], P < 0.001, I2 = 91.37%, studies: n = 79). Section 3.2, sentence 1: In the sentence beginning ‘The details of...’, the number ‘n = 4719’ should have read ‘n = 4843’. Section 3.4, paragraph 1, sentence 3: In the sentence beginning ‘Pairwise meta-analysis...’, the value ‘I2 = 92.4%’ should have read ‘I2 = 92.46%’, the value n = 251 should have read n = 253. Section 3.4, paragraph 1, sentence 4: In the sentence beginning ‘There was no...’, the value ‘P = 0.249’ should have read ‘P = 0.250’.
