Abbreviations: SMD, standardized mean difference; WMD, weighted mean difference; CI, confidence interval.
Non-active control defined as usual care, attention control, waitlist control or sham control.
A negative SMD or WMD suggests that the intervention is better than control at reducing fatigue severity.
Directionality of this scale was inverted for synthesis to be consistent with the other scales for WMD and to permit calculation of SMD.
