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

objectivesJumping mechanography is a common method to analyze muscle function. To date, mainly age- or weight-specific pediatric reference centiles for jumping mechanography have been published. The use of age-related references in children with small stature (defined as height below the age-specific third centile) might lead to misinterpretation of actual jumping performance. Thus, the study aim was the development of height-specific mechanography reference centiles of healthy children and show application in children with small stature.

methodsData from 882 children (aged 6-18 years; height 100-200cm) from the DONALD cohort was analyzed using the LMS (lambda-mu-sigma)-method. Sex-specific centiles were calculated for maximal velocity (Vmax), Nerve-Muscle Index (NMI), maximal power (Pmax) and maximal force (Fmax), both related to body mass. Age- and height-specific jumping parameters were individually compared in healthy children with small stature.

resultsVmax, Pmax and NMI increased with higher stature until a plateau was reached. Fmax stayed rather stable over time. Age-specific z-scores of Vmax, Pmax and NMI in children with small stature were lower than the height-specific z-scores.

conclusionsIn this article first height- and sex-specific reference centiles for jumping mechanography in healthy German children are presented. This study highlights the beneficial application of height-specific reference centiles for interpretation of jumping performance in children with small stature.
