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
Purpose: Sleep disorder is a frequent postoperative complication after total hip arthroplasty (THA). This study aimed to characterize sleep disorder phenotypes, identify associated risk factors, and explore the relationships between sleep disturbance patterns and clinical outcomes in elderly patients aged ≥70 years. Materials and Methods: A single-center retrospective analysis included 892 primary THA patients between January 2021 and December 2024. Sleep disorders were assessed via a validated 12-item questionnaire and diagnosed according to the International Classification of Sleep Disorders, 2nd Edition. Visual analog scale (VAS) pain scores and length of hospital stay (LOS) were extracted and stratified by different groups. All patients finished a minimum 6-month postoperative follow-up. Results: 78.3% of patients had postoperative sleep disturbances (median 6 weeks, range 4-8 weeks). Primary insomnias (72.1%) dominated, with adjustment sleep disorder (41.5%) most common; secondary insomnias (27.9%) linked to comorbidities (19.7%) and drugs (8.2%). Elderly patients had 83.5% incidence and 3.2-fold higher risk of persistent disturbances versus non-elderly patients ( Discussion: Pain (38.6%), psychological stress (29.4%), and intrinsic factors (16.2%) were most commonly associated with sleep disturbances. Elderly patients were more vulnerable to comorbidity-related and environmental sleep disruptors. Differences in clinical indicators were observed between patients receiving personalized perioperative management and those under routine care. Conclusions: Adjustment sleep disorder is the most common postoperative sleep phenotype in THA patients. Pain, psychological factors, and intrinsic characteristics are key drivers. In addition, patients with difficulty in staying asleep and non-restorative sleep are associated with higher pain scores and prolonged LOS. Elderly patients are high-risk for persistent sleep disturbances and inferior recovery outcomes. These findings suggest potential directions for patient-centered perioperative management, while relevant associations need further verification.
