Construct validity of the international physical activity questionnaire using accelerometry data in patients with femoroacetabular impingement Syndrome and Acetabular Dysplasia: a cross-sectional analysis.
Article in BMC musculoskeletal disorders, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper, 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
backgroundThe International Physical Activity Questionnaire (IPAQ) is widely used to assess physical activity (PA), but its validity compared to device-measured PA data in patients with Femoroacetabular Impingement Syndrome (FAIS) and Acetabular Dysplasia (AD) remains underexplored. We evaluated the convergent and divergent aspects of construct validity of self-reported PA via the IPAQ versus accelerometry data in patients with pre-arthritic hip diseases (FAIS, AD).
methodsParticipants with FAIS or AD, aged 18 and older, completed the IPAQ and wore accelerometers for 7 days. We compared IPAQ-reported moderate-to-vigorous physical activity (MVPA) with accelerometer-measured sedentary behavior, light PA, and MVPA using Pearson correlations and Bland-Altman plots.
resultsFifty-four individuals with FAIS or AD participated. We did not find any significant correlations between IPAQ-MVPA and accelerometer-measured PA variables. Bland-Altman plots revealed a positive systematic bias between IPAQ-MVPA scores and accelerometer-measured MVPA.
conclusionsThe IPAQ-MVPA scores showed divergent validity compared to accelerometer data in individuals with FAIS and AD. Future studies should integrate both self-report and device-based measures to enhance accuracy.
