Sleep disorders in primary antiphospholipid syndrome.

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
The objective of this study was to evaluate the sleep quality, the presence of sleep disorders in patients with primary antiphospholipid syndrome (pAPS), and their possible clinical and laboratory associations. This was a cross-sectional study of 40 consecutive pAPS patients and 211 healthy age- and sex-matched controls. Demographic and clinical data, drug use, and antiphospholipid antibodies were evaluated. Sleep was evaluated using the Pittsburgh Sleep Quality Index (PSQI). pAPS patients had significantly worse sleep quality than healthy controls. Analyzing the individual components, pAPS had worse scores in five of seven components: sleep duration (p = 0.002), habitual sleep efficiency (p = 0.003), sleep disturbance (p < 0.001), use of sleep medication (p < 0.001), and daytime somnolence (p = 0.03). No association of sleep disturbance and demographic, clinical, and laboratory features of the disease was observed. This is the first study to analyze sleep quality in pAPS. We observed that pAPS had significant worse sleep quality; however, no demographic, clinical, or laboratory feature was associated with sleep disturbance.
