Predicting Minute Ventilation from Heart Rate in Adolescents: A Tool for Environmental Health Studies.
Article in Environments (Basel, Switzerland), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the 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.
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
Minute ventilation (VE) is central to understanding the interplay between air pollution and exercise. However, real-time measurement of VE in environmental health research is often limited by access to equipment and technical expertise. We aimed to (1) develop predictive equations for VE based on heart rate (HR) in adolescents using metabolic exercise testing data, (2) evaluate which demographic factors influenced model accuracy, and (3) compare our equations to previously published equations applied to our sample. We analyzed cardiopulmonary exercise test (CPET) data from 41 patients. VE was log-transformed, and generalized estimating equations (GEE) were used to model associations between HR and VE, adjusting for age, sex, race, ethnicity, and BMI. In the fully adjusted model, HR was a strong predictor of VE (
