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
backgroundBoth the basal metabolic rate (BMR) and excess postexercise oxygen consumption (EPOC) can be influenced by physical training and are associated with body composition and aerobic capacity. Although a correlation between the two is expected, this relationship has not been explored. Our hypothesis is that a higher BMR is correlated with lower EPOC.
methodsFifty-four healthy participants with a mean age of 33 years were enrolled and instructed to visit the exercise laboratory five times within a 3-week period. These visits included one for the BMR measurement, one for the incremental exercise test (INC), and three for the constant work rate (CWR) test at low (35% of the maximal work rate, 15 min), moderate (60%, 10 min), and high intensities (90%, 4 min). The CWR tests were conducted at low, moderate, and high intensities in random order. After each CWR test, the EPOC and the ratio of EPOC to oxygen consumption during exercise (OC) were calculated. Venous blood samples were collected immediately to assess the blood lactate concentration (BLa).
resultsThe EPOC, EPOC/OC, and BLa increased with increasing intensity of the CWR tests. BMR exhibited an inverse correlation with EPOC/OC across the three CWR settings with correlation coefficients -0.449 in low (p = 0.003), -0.590 in moderate (p = 0.002), and -0.558 in high intensity (p < 0.001). In the stepwise regression analysis, the BMR emerged as the most significant predictor of EPOC/OC compared to the BLa, age, BMI, and various parameters derived from the INC and CWR CPET. Additionally, coupling EPOC/OC with CWR exercises of identical duration and relative intensity provides a viable method for interindividual comparisons.
conclusionsThe BMR is a major predictor of EPOC/OC and demonstrates a negative linear correlation across various CWR intensities. This study improves the understanding of the physiological link between BMR and EPOC and introduces an applicable approach for utilizing EPOC in future research.
