Description of age- and sex-specific reference values for cardiorespiratory fitness in healthy ethnic Kazakh adults: a cross-sectional study.
Article in Future science OA, 2026. 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
backgroundCardiorespiratory fitness (CRF) is a strong predictor of cardiovascular morbidity and mortality. This study aimed to describe age- and sex-specific reference values for CRF in healthy adults in Kazakhstan and to examine age-related changes in key physiological parameters, including peak heart rate and body mass index.
methodsThe research included 3271 nonsmoking adults aged 20 to 59 years, free of health issues, who performed symptom-limited incremental cardiopulmonary exercise testing on a cycle ergometer between 2018 and 2025. The highest 30-s average value from exercise testing defined peak oxygen uptake (VO

conclusionThis study provides the first nationally relevant descriptive data on CRF reference values for Kazakh adults.
