In-Field Validity and Inter-Unit Variability of Metabolic Carts During Simulated Exercise.
Article in Scandinavian journal of medicine & science in sports, 2026. 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
The present study had three main objectives: (a) to evaluate the in-field validity of different commercially available cardiopulmonary exercise testing (CPET) systems when used by end-users following typical calibration procedures, (b) to measure the variability in accuracy among identical CPET units, and (c) to explore the relationship between the age of the units, as well as the maintenance practices, and their measurement accuracy. Fifty-seven CPET systems, calibrated and operated by end-users in clinical practice, research, or sports settings, were assessed against a metabolic simulator that simulates breath-by-breath gas exchange. The values measured by each system [minute ventilation (V̇E), oxygen uptake (V̇O
