OMERACT Filter 2.1 instrument selection for physical function domain in psoriatic arthritis: Provisional endorsement for HAQ-DI and SF-36 PF.
Article in Seminars in arthritis and rheumatism, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled it.
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
objectivesPhysical function is one of the core domains to be measured in all trials in psoriatic arthritis (PsA). We aimed to evaluate two instruments for physical function in PsA: The Health Assessment Questionnaire-disability index (HAQ-DI) and the physical functioning subscale of the Medical Outcome Survey Short-Form 36 items (SF-36 PF).
methodsWe followed guidelines set out by the OMERACT Filter 2.1. A working group was formed to evaluate each instrument for domain match and feasibility to reach consensus. Two systematic literature reviews (SLRs) were conducted to identify the relevant articles supporting measurement properties of both instruments. Five additional measurement properties were appraised: construct validity, test-retest reliability, longitudinal construct validity, clinical trial discrimination, and threshold of meaning. New evidence was synthesized to fill the gap. Data were presented to the OMERACT technical advisory group (TAG) and the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) community for endorsement.
resultsThe results for seven measurement properties for HAQ-DI and SF-36 PF were presented in Summary of Measurement Property (SOMP) tables. The working group proposed "Provisional Endorsement" for both instruments. The body of evidence was approved by the OMERACT TAG. In two Delphi exercises among GRAPPA members, HAQ-DI received 93.9% and 97.5% endorsement votes, while that for SF-36 PF were 86.7% and 77.3%.
conclusionBoth HAQ-DI and SF-36 PF were provisionally endorsed for the measurement of physical function in PsA trials, using the OMERACT Filter 2.1.
