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

The aim of the study was to compare vertical jumping performances in boys and girls during growth. The maximum heights attained in a countermovement jump (CMJ) and squat jump (SJ) were measured using an Ergojump Bosco System. Average power output (PO) was recorded, and percentage of fast-twitch (%FT) muscle fiber distribution was estimated during the rebound jump. Differences in the maximum CMJ and SJ (CMJ-SJ) heights were calculated. Regressions between PO and age, lean body mass (LBM), and leg muscle volume (LMV), respectively, were computed for 240 boys and 239 girls (aged 11-16 years). Height, LMV, and body mass values were larger in boys than girls aged 14 years. Both groups had a similar body mass index independently of age. The CMJ, SJ, PO, and %FT were larger in boys than in girls between 12 and 16 years of age. Strong correlations were found between PO and age in the population as a whole, and between PO and LBM, PO and LMV in each group. The CMJ-SJ decreased with increasing age in both groups without significant differences. Conclusion Jumping performance increases during growth, with gender differences manifesting from 14 years onwards due to the much greater increase in leg length and LMV in boys than in girls.
