Abnormal Sleep in Chronic Inflammatory Demyelinating Polyneuropathy.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
BACKGROUND AND
objectivesChronic inflammatory demyelinating polyneuropathy (CIDP) is a dysimmune disease leading to sensorimotor deficits due to peripheral nerve dysfunction, but recently additional non-sensorimotor symptoms (NSMS) were increasingly recognized. In this context, we compared the sleep behavior in persons with versus without CIDP and discussed the results with respect to further NSMS.
methodsTwenty-five CIDP patients and 27 controls took part in this prospective, cross-sectional study. Clinically, sensorimotor disability (RODS), affective state (DESC-I), and fatigue levels (FSMC scores) were assessed. Regarding sleep-wake behavior, they wore actigraphic devices over 14 consecutive days and completed sleep diaries, chronotype questionnaires, and the Pittsburgh Sleep Quality Index (PSQI). The actigraphic data were analyzed with respect to sleep efficiency, wake after sleep onset (WASO), sleep onset latency, total sleep duration, intradaily variability (IV), and interdaily stability (IS).
resultsPatients with CIDP reported significantly worse subjective sleep quality (p < 0.001). They also showed higher levels of fatigue (p < 0.001) and depressiveness (p = 0.046). The actigraphic results showed significantly reduced WASO (p DISCUSSION: Beyond subjectively reduced sleep quality, actigraphic data show that persons with CIDP have lowered sleep efficacy and experience increased nocturnal arousals. This suggests that sleep disturbance is a genuine aspect of CIDP adding to the underrecognized problem of NSMS in this condition.
