Effects of maturity status on the rate of torque development in young male soccer players.
Article in BMC pediatrics, 2024. 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
backgroundThe rate of torque development (RTD) has been associated with sports performance and can be improved during the biological maturation process of young soccer players. The aim of this study was to compare the effects of maturity status on the knee extensors' RTD of soccer players after appropriate normalization.
methodsTwenty-seven young male soccer players aged 13-18 years old were allocated into two groups: pubescent (PUB, n = 11) and postpubescent (POSP, n = 16). RTD was obtained by performing a maximum voluntary isometric contraction at six different knee joint angles (30º, 45º, 60º, 75º, 90º, and 105º). Anthropometric (height and body mass) and muscle architecture variables (muscle thickness, muscle volume, fascicle length, pennation angle, and cross-section area) were evaluated as body size descriptors and used to identify the best way for appropriate normalization of RTD data.
resultsMuscle architecture variables showed no correlations with RTD (p > 0.05), while body mass showed a positive correlation (0.405 < r < 0.680; p < 0.05). Maturity status showed positive effects on absolute late RTD values (N·m·s
conclusionsMaturity status showed no positive effects on RTD values after appropriate normalization by body mass in young soccer players.
