Prevalence and impact of sleep disorders in osteoarthritis: A systematic review and meta-analysis.
Article in Osteoarthritis and cartilage open, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objective: Sleep disorders (SD) are increasingly recognized as a major contributor to the symptom burden of osteoarthritis (OA), yet their epidemiology and clinical impact remain insufficiently characterized. This systematic literature review with meta-analysis aims to quantify the prevalence of SD in OA patients and to assess their influence on patient-reported outcomes. Method: We searched the PubMed, Embase, Web of Science and Cochrane Library databases up to 22 July 2025 (PROSPERO CRD120251067310). The Pittsburgh Sleep Quality Index (PSQI), sleep efficiency, and the number of patients with SD, including insomnia, sleep apnea and restless legs syndrome (RLS) were collected. The prevalence of SD was calculated using metaproportion. Differences were measured using the inverse variance method or the Mantel-Haenszel method. Results: We selected 81 articles representing 289,914 patients, including 75,129 knee, 708 hand and 236 hip OA. For the remaining patients, OA location was not noticed or multiple. The prevalence of SD was 68.9 % (63 studies, 276,092 patients), 32.0 % for sleep apnea, 34.0 % for insomnia and 51.6 % for RLS. Compared to healthy controls, the prevalence of SD was higher in OA patients which had poorer sleep quality with a higher PSQI score (7.9 ± 3.4 vs. 6.5 ± 2.7; p = 0.002) and lower sleep efficiency (82.1 ± 12.5 vs. 89.8 ± 6.0 %; p = 0.02). OA patients with SD were younger, had a higher BMI, a greater pain intensity and a higher frequency of depression and catastrophizing. Conclusion: Sleep disorders are common in OA patients and should be investigated and managed since they have a negative impact on pain, fatigue and disability.
