The dRM-Index: Applicability of the Differential Respiratory-to-Muscular Training Load Index in Young Female Soccer Players.
Article in Journal of human kinetics, 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
This study described the differential respiratory and muscular perceived training loads (RPEres-TL and RPEmus-TL) within and between sessions, and investigated the associations between neuromuscular performance and the dRM-Index (i.e., the ratio of differential respiratory and muscular perceived training loads: RPEres-TL divided by RPEmus-TL) among youth female soccer players. Thirteen outfield players (age: 17 ± 1 years) of the third team of a Women's Soccer Spanish First Division Club completed the 14-week study period. Neuromuscular performance tests (countermovement jump [CMJ], CMJ arm swing, single leg CMJ, and 30-m sprint tests) were conducted before (T1) and after (T2) the study period. Players improved neuromuscular performance (p < 0.05; Cohen's d < 1.29; small-to-large) from T1 to T2. RPEres-TL was greater than RPEmus-TL for training sessions performed four (M-4: p < 0.001; Cohen's d = -0.61; moderate) and one (M-1: p = 0.01; Cohen's d = -0.37; small) days before the match. Baseline sprint performance showed large correlations with the dRM-Index during M-2 (p < 0.05; r < 0.59), M-1 (p < 0.05; r < 0.60) and matches (p < 0.05, r < 0.66). Differential RPE allows the analysis of the TL distribution during the week providing additional insights into the training workload. Baseline sprint performance can be used to forecast the differed heterogeneous individual cardiovascular and neuromuscular responses to the sessions. This initial study on the dRM-Index offers a novel and practical approach to individualize and optimize the training process of youth female soccer players.
