Health‐related quality of life Self‐assessed questionnaires Follow‐up: 6‐12 weeks | Mean health‐related quality of life in intervention groups was 0.04 standard deviations lower (0.30 lower to 0.23 higher) | 233 (3 studies) | ⊕⊝⊝⊝ Very lowa,b,c,d | SMD ‐0.04 (95% CI ‐0.30 to 0.23) |
Fatigue Self‐assessed questionnaires Follow‐up: 6‐12 weeks | Mean fatigue in intervention groups was 0.21 standard deviations lower (0.66 lower to 0.25 higher) | 233 (3 studies) | ⊕⊝⊝⊝ Very lowa,b,c,d | SMD ‐0.21 (95% CI ‐0.66 to 0.25) |
*The basis for the assumed risk (e.g. median control group risk across studies) is provided in footnotes. The corresponding risk (and its 95% confidence interval) is based on assumed risk in the comparison group and the relative effect of the intervention (and its 95% CI). CI: confidence interval; SMD: standardised mean difference. | ||||
GRADE Working Group grades of evidence. High quality: Further research is very unlikely to change our confidence in the estimate of effect. Moderate quality: Further research is likely to have an important impact on our confidence in the estimate of effect and may change the estimate. Low quality: Further research is very likely to have an important impact on our confidence in the estimate of effect and is likely to change the estimate. Very low quality: We are very uncertain about the estimate. |
aDowngraded one level because of overall unclear risk of bias. bDowngraded two levels because the 95% confidence interval includes no effect. cDowngraded one level because fewer than 400 participants were included in the total. dDowngraded two levels because the 95% confidence interval includes no effect.
