Table 3 Methods of measuring primary outcomes and summary of finding (SoF). GRADEprofiler was used to create the table.

SCOPA (daytime sleepiness) – Scales for Outcomes in Parkinson’s Disease (daytime sleepiness); PDSS – Parkinson’s Disease Sleep Scale; FSS – Fatigue Severity Scale; FIS – Fatigue Impact Scale; BBS – Brief Bronowski Scale; BAI – Beck Anxiety Inventory; PDQ-39; WHO-QOL – World Health Organization-Quality of Life assessment. * The basis for the assumed risk (e.g. the median control group risk across studies) is provided in footnotes. The corresponding risk (and its 95% confidence interval) is based on the assumed risk in the comparison group and the relative effect of the intervention (and its 95% CI). CI – confidence interval; RR – risk ratio; GRADE Working Group grades of evidence. Further research is very unlikely to change our confidence in the estimate of effect. Further research is likely to have an important impact on our confidence in the estimate of effect and may change the estimate. 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. We are very uncertain about the estimate. |
