Polysomnographic and multiple sleep latency testing data in a large sample of patients with chronic fatigue syndrome and their relationship with subjective scores.
Abstract
Background: Despite the majority of patients with chronic fatigue syndrome (CFS) complaining about sleep disturbances and/or non-refreshing sleep, abnormalities in objective sleep parameters have not consistently been identified in this population. Purpose: To assess objective parameters of sleep and sleepiness in a large sample of patients with CFS and their relationship with the subjective dimensions of mental and physical health, sleep quality, daytime sleepiness and fatigue. Methods: Objective sleep parameters were derived from polysomnography (PSG) and multiple sleep latency testing (MSLT). Subjective scores for mental and physical health, sleep quality, daytime sleepiness and fatigue were based on validated, self-report questionnaires. Hierarchical multiple regression analysis was performed to predict sleepiness, global quality of sleep and fatigue. Results: PSG in 184 CFS patients indicated decreased total sleep time and sleep efficiency as well as increased sleep latency and waking after sleep onset. Only a few modest but significant correlations (r’s < .30) were found between objective parameters of sleep and sleepiness and subjective scores for health, sleep quality and fatigue. Conclusions: Objective sleep parameters indicated poor sleep in CFS, suggesting an insomnia phenotype, but with only modest associations to subjective scores of mental and physical health, sleep quality, daytime sleepiness and fatigue.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
