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
backgroundSleep disorders are closely linked to the onset, progression and severity of psychiatric disorders, yet large-scale data from real-world inpatient settings remain limited. Evaluating the impact of chronic sleep disorders (CSD) in this context is essential for improving care.
methodsWe conducted an analysis of adult inpatients hospitalized from January 1, 2021, to December 31, 2023, using data from the Paris Psychiatry Hospital Group's health data warehouse. Sleep disorders were identified via ICD-10 codes, hypnotic prescriptions, or mentions in medical record. CSD was defined using an Index of Length of Stays with Disorders (ILSD) >0.5, and no sleep disorders (NSD) with an ILSD of zero.
resultsAmong 13,913 psychiatric inpatients, 81% were classified as having CSD. Compared to NSD patients, those with CSD had a higher number of hospitalizations (1.84 vs 1.33, p<0.001) and increased use of seclusion (17.6% vs 13.3%, p<0.001) and physical restraint (6.6% vs 5.3%, p=0.003). Individuals with CSD were more frequently hospitalized than the NSD group for depressive disorders (15.6% vs13.1%, p<0.001), bipolar disorders (11.4% vs5.6%, p<0.001), personality disorders (5.3% vs4.3%, p=0.009), alcohol abuse (3.3% vs2.4%, p=0.005), other substance use disorders (2.9% vs2.2%, p=0.018), manic episode (2.0% vs0.9%, p<0.001), and anxiety disorders (1.4% vs0.9%, p=0.012). Hypnotics were prescribed in 50.5% of SD-related stays. The CSD group had more psychiatric and non-psychiatric comorbidities.
conclusionsCSD are highly prevalent in psychiatric inpatients and associated with more severe clinical profiles, greater hospitalization burden, and increased restraint use. Targeted sleep management strategies may help improve outcomes and care.
