1 · What the graph read from it

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.

2 · The registry

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

Short-term maximum intensity performance, absolute and related to body mass, is lower in children than adolescents. The underlying mechanisms are not clear. We analysed Wingate Anaerobic Test (WAnT) performance and metabolism in ten boys (mean (SD); age 11.8 (0.5) years, height 1.51 (0.05) m, body mass 36.9 (2.5) kg, muscle mass 13.0 (1.0) kg) and 10 adolescents (16.3 (0.7) years, 1.81 (0.05) m, 67.3 (4.1) kg, 28.2 (1.7) kg). Related to body mass, power of flywheel acceleration (6.0 (1.6) vs. 8.1 (1.1) W kg(-1)), peak power (10.8 (0.7) vs. 11.5 (0.6) W kg(-1)), average power (7.9 (0.5) vs. 8.9 (0.7) W kg(-1)), minimum power (6.1 (0.7) vs. 6.9 (0.9) W kg(-1)) and anaerobic lactic energy (687.6 (75.6) vs. 798.2 (43.0) J kg(-1)) were lower (P < 0.05) in boys than in adolescents. Related to muscle mass the change in lactate (0.69 (0.08) vs. 0.69 (0.04) mmol kg (MM) (-1) s(-1)) and PCr (0.60 (0.17) vs. 0.52 (0.10) mmol kg (MM) (-1) s(-1)) were not different. The corresponding oxygen uptake (1.34 (0.13) vs. 1.09 (0.13) ml kg (MM) (-1) s(-1)), total metabolic rate (132.4 (12.6) vs. 119.7 (8.5) W kg (MM) (-1) ) and PP (30.5 (2.6) vs. 27.5 (1.7 W) kg (MM) (-1) ) were higher (P < 0.01) in boys than in adolescents. The results reflect a lower relative muscle mass combined with no differences in muscular anaerobic but fascilitated aerobic metabolism in boys. Compared with adolescents, boys' performance seemed to be significantly impaired by flywheel inertia but supported by identical brake force related to body mass.
