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

Jumping mechanography is a tool for dynamic assessment of muscle function. We present the largest available reference data set to date for jumping mechanography in children and adolescents. Jumping mechanography reference data serve as a crucial benchmark for evaluating muscle and bone health outcomes in children and adolescents.

backgroundWe aimed to develop age- and sex-specific reference data for jumping mechanography measures in Canadian children and adolescents.

methodsData from over 3000 children and adolescents (50.0% females) aged 6-20 years were obtained from the Canadian Health Measures Survey cycles 5 and 6 (2016-2019), a national, cross-sectional, population-based study. Muscle function was measured using the Leonardo Mechanograph Ground Reaction Force Plate through the single two-legged jump (S2LJ) and multiple two-legged hopping (M2LH) tests. Reference data were generated for maximum power, maximum power relative to body mass, maximum jump height, and maximum jump velocity from the S2LJ, and maximum force as well as maximum force relative to body weight from the M2LH.

resultsMale and female results were similar at age 6 years. However, males experienced greater increases in muscle function compared to females (e.g., the median result for maximum power in the S2LJ increased by 441% from age 6 to 16 years in males vs 297% in females). In males all outcome measures continued to increase to age 20 years, whereas in females absolute force and power plateaued after the age of 16 years. Body mass dependent outcome measures decreased slightly in females after 16 years of age, due to rising body mass.

conclusionThis study provides the largest jumping mechanography reference dataset to date, aimed at helping clinicians assess muscle function and evaluate musculoskeletal health in children and adolescents.
