Validity and reliability of the K5 wearable metabolic system during high-intensity treadmill testing in healthy, young adults.

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
backgroundThe COSMED K5 portable metabolic system (K5) enables field-based assessments of gas exchange variables. This study evaluated the validity and test-retest reliability of K5 relative to the laboratory-based ParvoMedics TrueOne2400
methodsThirty-one adults (mean age 25.8 ± 2.8 years, 61.3% male) completed three Bruce protocol CPET trials: one using PM and two using K5. The order of the first two trials was randomized and counter balanced; the third used K5. Breath-by-breath data were averaged over the final 90 seconds of each CPET stage. Validity was assessed using paired comparisons and Bland-Altman analyses. Reliability was evaluated using intraclass correlation coefficients (ICC).
resultsThe K5 demonstrated excellent test-retest reliability for oxygen consumption (VO
conclusionsThe K5 is a valid and reliable device for treadmill CPET in healthy young adults. Small systematic differences exist relative to PM at extreme workloads yet remain within acceptable clinical limits, supporting its utility for longitudinal and applied assessments requiring portability.
