1 · What the graph read from it

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.

2 · The registry

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

objectiveSleep disturbances and epilepsy are closely interrelated. This study aimed to examine associations between sleep quality, affective symptoms, and quality of life (QoL) in people with epilepsy (PWE), and to identify clinical and sociodemographic factors linked to impaired sleep.

methodsWe conducted a multicenter cross-sectional study of adult PWE across four tertiary epilepsy centers in Germany. We assessed sleep quality using the Pittsburgh Sleep Quality Index (PSQI), affective symptoms with the Hospital Anxiety and Depression Scale (HADS), and epilepsy-specific QoL with the 31-item Quality of Life in Epilepsy (QOLIE-31) inventory. We evaluated sociodemographic and clinical predictors of sleep quality and QoL using univariable and multivariable analyses. Comparisons were made with normative data from the general German population and individuals with chronic migraine.

resultsOf 449 individuals (mean age 39.9 years, 58.1% women), 221 (49.2%) were identified as "poor sleepers," significantly exceeding rates in the general population (35.9%, p < .001). In multivariable analysis, poor sleep quality was independently associated with female sex (odds ratio [OR] 2.02, 95% confidence interval [CI] 1.36-3.01, p = .001), unemployment (OR 1.74, 95% CI = 1.10-2.73, p = .017), anxiety (OR = 3.79, 95% CI = 2.39-6.04, p < .001), and depression (OR = 2.19, 95% CI = 1.36-3.54, p = .001). In addition, daily seizures were linked to worse sleep quality (OR = 2.55, 95% CI = 1.03-6.30, p = .042). Poor sleep was independently associated with lower epilepsy-related QoL after adjusting for affective symptoms and seizure frequency (OR = 1.79, 95% CI = 1.20-2.68, p = .005). SIGNIFICANCE: Sleep quality in PWE is significantly impaired and strongly associated with anxiety, depression, and sociodemographic variables in addition to epilepsy-specific factors. Poor sleep independently correlates with diminished QoL, supporting the value of routine screening for affective symptoms and sleep disturbances in epilepsy care.
