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
backgroundClinically relevant fatigue in rheumatoid arthritis (RA) patients significantly affects their quality of life. Almost all studies have assessed fatigue in this population using non-specific scales. The present multi-centric study aimed to assess the validity, reliability, and clinical significance of the Arabic version of the Bristol Rheumatoid Arthritis Fatigue Multi-Dimensional Questionnaire (BRAF-MDQ).
methodsThe present cross-sectional multicentric study was conducted at Aswan, Mansoura, Port Said, and Al-Azhar University Hospitals over a 6-month duration. The study included 311 patients with RA diagnosed according to the 2010 criteria of the American College of Rheumatology. The Arabic version of BRAF-MDQ was developed to assess fatigue in these patients. All patients were subjected to careful history taking, thorough clinical assessment, and standard laboratory work-up. The obtained Arabic BRAF-MDQ was tested for construct validity, internal consistency, testretest reproducibility, and criterion validity. Construct validity was evaluated using factor analysis with the Kaiser Meyer Olkin tool of sampling adequacy and Bartlett's sphericity test. Internal consistency of subscales was assessed using Cronbach's alpha. Test-retest reproducibility was assessed after a 1-week interval using the intraclass correlation coefficient. Pearson's correlation coefficient was used to correlate numerical variables. Predictors of fatigue were identified using binary logistic regression analysis.
resultsThe present study included 311 RA patients. Construct validity assessment showed a high loading of questionnaire items within the proposed construct subscales with a KMO measure of sphericity of 0.927 and Bartlett's test of sphericity p-value < 0.001. Internal consistency assessment showed adequate Cronbach's alpha of Arabic BRAF-MDQ subscales. Total Arabic BRAFMDQ had excellent criterion validity, as indicated by the high correlations with MAFS (r=0.95, p < 0.001) and SF-36 vitality subscale (r=-0.91, p < 0.001). Clinically significant fatigue was identified in 214 patients (68.8%). Multivariate logistic regression analysis revealed age (OR (95% CI): 1.07 (1.02-1.12), p < 0.001), disease duration (OR (95% CI): 1.82 (1.43-2.33), p < 0.001), DAS28<sub.CRP</sub. (OR (95% CI): 8.62 (4.63-16.02), p < 0.001), and mHAQ (OR (95% CI): 3.85 (1.07-13.9), p = 0 .039) as significant predictors of fatigue development in the studied patients.
conclusionThe Arabic version of the Bristol Rheumatoid Arthritis Fatigue Multi-Dimensional Questionnaire is a valid, consistent, and reliable tool for the assessment of fatigue in Egyptian rheumatoid arthritis patients. Clinically significant fatigue was identified in 214 patients (68.8%). Further, risk factors for fatigue included older age, longer disease duration, and higher disease activity.
