Development and psychometric validation of the 13-item physician health and quality of life (Afya MedQoL) index: a nationwide cross-sectional survey of Brazilian physicians.
Article in BMJ open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectivesTo develop and validate a concise, physician-specific quality-of-life scale (Afya MedQol) Index, and to examine sociodemographic and occupational correlates of physician well-being in Brazil.
designNation-wide, cross-sectional, web-based survey employing split-sample psychometric validation: exploratory factor analysis, confirmatory factor analysis (CFA), multidimensional graded-response item-response theory calibration and post-stratification weighting to the 2025 Brazilian medical demographic census.
settingPhysicians practising in all five Brazilian macro-regions and 27 state medical councils (2 July 2024-6 August 2024).
participantsA total of 2005 fully responding physicians (56% women; mean age 38.5±12.6 years). PRIMARY OUTCOME MEASURES: Domain scores-F1: Quality of Life, F2: Institutional Support, F3: Perceived Stress-and a Fisher-information-weighted global score. Convergent validity with WHOQOL-Bref; subgroup differences (Cohen's d, partial η²).
resultsCFA supported a three-factor, 13-item solution (Comparative Fit Index=0.987; Root Mean Square Error of Approximation=0.050) with strict invariance across sex and graduation-year quartiles. Item-response modelling showed marginal reliability ρ=0.82. Convergent validity with WHOQOL-Bref domains was strong (r=0.55-0.73). Weighted mean (95% CI) scores were: Global 67.2 (66.5-67.9), F1 69.5 (68.9-70.2), F2 64.1 (63.4-64.8) and F3 62.5 (61.8-63.2).Women scored higher on Perceived Stress (F3) than men by 5.6 points (weighted mean difference 5.6, 95% CI 4.0 to 7.2; Cohen's d 0.28). Physicians working ≥60 hours/week scored higher on Perceived Stress than those working ≤44 hours/week by 8.8 points (weighted mean difference 8.8, 95% CI 6.7 to 10.9; Cohen's d 0.40). Well-being increased with income up to ~BRL 25 000 per month and plateaued thereafter.
conclusionsAfya MedQoL Index is a psychometrically robust, 13-item instrument capturing personal, organisational and stress dimensions of physician well-being. Perceived Stress-shaped by workload, institutional climate and gender-was the most discriminative domain, while additional income beyond an upper-middle-class threshold conferred negligible benefit. Findings support policies aimed at capping duty hours, fostering 'just-culture' environments and expanding flexible work models.
