Measurement properties of the incremental step test for people with chronic obstructive pulmonary disease: a cross-sectional study.
Article in BMJ open, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04715659 (A Novel Incremental Step Test as an Alternative for the Assessment of Exercise Capacity in Patients With COPD - The Study of Its Measurement Properties), which is not on this map. Not yet cited in PubMed.
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.

Abstract
objectivesThe new incremental step test (IST) is a field test that was developed for people with chronic obstructive pulmonary disease (COPD), based on the characteristics of the incremental shuttle walk test (ISWT); however, its measurement properties still need to be determined. We aimed, first, to assess the construct validity (through the comparison with the ISWT), within-day reliability and measurement error of the IST in people with COPD; and, second, to identify whether the participants have a learning effect in the IST.
designCross-sectional study, conducted according to COnsensus-based Standards for the selection of health status Measurement INstruments guidelines.
settingA family health unit in Portugal, April 2022 to June 2023. PARTICIPANTS AND ANALYSIS: 63 participants (67.5±10.5 years) attended two sessions to perform two IST and two ISWT, separately. Spearman's correlations were used to compare the best performances between the IST and the ISWT. Intraclass correlation coefficient (ICC
resultsThe IST was significant and strongly correlated with the ISWT (0.72<ρ<0.74, p<0.001), presented an ICC
conclusionsThe IST can be suggested as a valid and reliable test to assess exercise capacity in people with COPD, with no learning effect when two IST are performed on the same day. The measurement error of the IST is considered indeterminate. TRIAL REGISTRATION NUMBER: NCT04715659.
