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
INTRODUCTION/
objectivesThis study provides a novel comparison of sleep disturbances and associated risk factors in rheumatoid arthritis (RA), axial spondyloarthritis (axSpA) and psoriatic arthritis (PsA), and assesses the correlation between the Multidimensional Health Assessment Questionnaire (MDHAQ) and the Pittsburgh Sleep Quality Index (PSQI) in detecting poor sleep.
methodWe performed a cross-sectional study of 313 adult patients included in the PolNorRHEUMA registry. Demographics, disease activity, pain and other clinical variables were recorded. Patients completed a PSQI, with scores higher than 5 indicating poor sleep, and an MDHAQ, including queries concerning sleep, anxiety, depression, stress.
resultsThis study included 129 patients with RA, 81 with PsA and 103 with axSpA. The median disease activity scores corresponded to remission or low disease activity. The prevalence of poor sleep was 61.5% in PsA, 63.7% in RA, to 66.7% in axSpA; no significant differences in PSQI total scores or sleep domains were identified. Independent risk factors for poor sleep were female sex in RA, older age and anxiety in PsA. Strong correlation coefficients between the MDHAQ sleep-related question and PSQI score were observed: 0.53 for RA, 0.65 for PsA and 0.55 for axSpA (p < 0.01). In the linear regression analysis, a significant association was maintained in RA and axSpA.
conclusionsOur research confirms a high prevalence of sleep disturbances in RA, axSpA, and PsA, despite well-controlled disease activity, highlighting the role of non-inflammatory factors in the pathophysiology. The MDHAQ could serve as a screening tool for identifying poor sleep quality. Key Points •Poor sleep is prevalent among patients with RA, axSpA and PsA •Prevalence of sleep disturbances is high despite well-controlled disease activity. •Risk factors for poor sleep identified in this study include female sex in RA, and older age and anxiety in PsA. •The MDHAQ could serve as a screening tool for identifying patients with poor sleep quality, needing further evaluation.
