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
purposeThe association between moderate physical activity (MPA) and vigorous physical activity (VPA) with the risk of sarcopenia in adolescents remains unclear. This study aims to examine their relationships systematically.
methodThis study utilized NHANES data from 2011 to 2018 from 6,415 adolescent participants. Weighted logistic regressions were conducted to investigate the effect of MPV and VPA on the risk of sarcopenia. Using weighted logistic regression with restricted cubic splines (RCS) to model potential nonlinear associations, threshold effect analysis to identify critical inflection points, and likelihood ratio tests for model comparison. Based on these thresholds, participants were stratified into six MVPA exposure groups: no-moderate (MPA = 0), low-moderate (0 < MPA < threshold), high-moderate (MPA ≥ threshold), no-vigorous (VPA = 0), low-vigorous (0 < VPA < threshold), and high-vigorous (VPA ≥ threshold). Distinct exercise patterns were derived from systematic combinations of these exposure categories. Weighted logistic regression was used to analyze the effect of exercise pattern.
resultsAfter adjusting for multiple covariates, VPA decreased the risk of sarcopenia by 56%, whereas MPA reduced it by 24%. A "U-shaped" nonlinear relationship was observed between moderate physical activity (MPA), vigorous physical activity (VPA), and the risk of sarcopenia, with inflection points occurring at 40 min per week for MPA and 600 min per week for VPA. Nine distinct PA patterns were classified, ranging from patterns A to I. Compared to not engaging in any duration of VPA or MPA (pattern A), performing MPA < 40 min per week (pattern B; OR 0.63, 95%CI: 0.39, 1.04; P = 0.069) or engaging in VPA > 600 min and MPA > 40 min weekly (pattern I; OR 0.41, 95%CI: 0.17, 1.01; P = 0.052 ) did not reduce the risk of adolescent sarcopenia. Performing VPA > 600 min per week (pattern G) per week reduced risk of sarcopenia significantly (OR 0.13, 95%CI: 0.05, 0.35; P < 0.001).
conclusionsThis study reveals a nonlinear dose-response relationship between PA and sarcopenia risk in adolescents. Both insufficient and excessive exercise did not reduce adolescent sarcopenia risk. Performing VPA > = 600 min per week reduced risk of sarcopenia significantly.
