Construct Validity and Reliability of the 2-Minute Step Test in Patients with Fibromyalgia.
Article in European journal of rheumatology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Background: The aim of this study was primarily to assess the validity and reliability of the 2-minute step test (2MST) in patients with fibromyalgia; and secondly, to explore its relationship with the 2-minute walk test (2MWT), the 6-minute walk test (6MWT), as well as fatigue severity and quality of life. Methods: This cross-sectional study involved 55 female patients aged 18-65 diagnosed with fibromyalgia according to the American College of Rheumatology 2010 Diagnostic Criteria. Pain intensity was measured using the Visual Analog Scale, quality of life impact was assessed with the Fibromyalgia Impact Questionnaire, and fatigue severity was evaluated using the Fatigue Severity Scale. Patients underwent initial assessments using the 2MST, 2MWT, and 6MWT. Test-retest reliability of the 2MST was determined with a 7-day interval between assessments. Results: The study included a cohort of participants with an average age of 45.3 ± 7.7 years. The mean score for the 2MST was 51.9 ± 15.6, with a second 2MST yielding a mean score of 56.1 ± 16.4. The reliability of the 2MST was found to be good (ICC=0.925) in patients with fibromyalgia. The 2MSTexhibited significant correlations with the 2MWT (ρ=0.633) and 6MWT (ρ= 0.703). Conclusion: In conclusion, this study demonstrates that the 2MST is a reliable tool for evaluating exercise capacity in individuals with fibromyalgia, showing a negative association with age and pain severity.
