Validating the Michigan Hand Outcomes Questionnaire in patients with rheumatoid arthritis using Rasch analysis.
Article in PloS one, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
introductionThe Michigan Hand Outcomes Questionnaire (MHQ) is a patient-reported outcome measure previously validated in patients with rheumatoid arthritis (RA) using classical test theory. Rasch analysis is a more rigorous method of questionnaire validation that has not been used to test the psychometric properties of the MHQ in patients with RA. The objective of this study is to evaluate the validity and reliability of the MHQ for measuring outcomes in patients with RA with metacarpophalangeal joint deformities.
methodsWe performed a Rasch analysis using baseline data from the Silicone Arthroplasty in Rheumatoid Arthritis (SARA) prospective cohort study. All domains were tested for threshold ordering, item fit, targeting, differential-item functioning, unidimensionality, and internal consistency.
resultsThe Function and Work domains showed excellent fit to the Rasch model. After making adjustments, the Pain, Activities of Daily Living (ADL) and Satisfaction domains also fulfilled all Rasch model criteria. The Aesthetics domain met the majority of Rasch criteria, but could not be tested for unidimensionality.
conclusionsAfter collapsing disordered thresholds and removing misfitting items, the MHQ demonstrated reliability and validity for assessing outcomes in patients with RA with metacarpophalangeal joint deformities. These results suggest that interpreting individual domain scores may provide more insight into a patient's condition rather than analyzing an overall MHQ summary score. However, more Rasch analyses are needed in other RA populations before making adjustments to the MHQ.
