Measuring Work Related Physical and Mental Health Function: Updating the Work Disability Functional Assessment Battery (WD-FAB) Using Item Response Theory.
Article in Journal of occupational and environmental medicine, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
objectiveTo further improve measurement of work-related physical and mental health by updating the Work Disability Assessment Battery (WD-FAB).
methodsCross-sectional study with 1024 disability claimants and 1000 working age (21 to 66 years) adults in the United States. Developed new items to replenish the WD-FAB and analyzed using factor analysis and item response theory (IRT). Computer adaptive testing (CAT) simulations evaluated the psychometric properties of the original versus updated WD-FAB.
resultsAnalyses confirmed the structure of the WD-FAB. Twenty-three new items were added (basic mobility: 7, upper body function: 4, fine motor: 6, self-regulation: 1, resilience & sociability: 5 items).
conclusionsFindings support the WD-FAB as a robust, psychometrically sound assessment of work-related function. Extensive content coverage (331 items) represents eight physical and mental health domains. IRT/CAT methods allow administration in under 15 minutes. The WD-FAB may prove valuable for efficiently characterizing work-related function across work rehabilitation settings.
