Characterization of dysfunctional breathing using cardiopulmonary exercise testing.
Article in Physiological reports, 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
Cardiopulmonary exercise testing (CPET) is emerging as a useful tool in the identification of dysfunctional breathing (DB). We aimed to evaluate the prevalence and functional impact of different patterns of DB in 628 adult patients referred for CPET due to unexplained dyspnoea (August 2019-December 2023). Patients were assigned to four groups following CPET interpretation: normal, breathing pattern disorder (BPD), hyperventilation (HV), and combined BPD with HV (BPDHV). Demographic and CPET performance data were analyzed using non-parametric tests as appropriate. 94 (15.0%) patients had normal CPETs and 267 (42.5%) were identified as having DB. The remaining 267 were excluded as having alternative diagnoses. Of those with DB, 145 (54.3%) had BPD, 41 (15.4%) had HV, and 81 (30.3%) had BPDHV. VE/VCO
