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

This 12-week, four-arm randomized controlled trial examined whether weekly frequency of school-based high-intensity interval training (HIIT) differentially affects adiposity and cardiorespiratory fitness in children with obesity. Sixty participants aged 10-12 years were randomized to a control group or HIIT performed 1, 2, or 3 times per week during physical education; 51 completed the study. Primary outcomes were body mass index (BMI)-z and 20 m shuttle run test (20mSRT) performance. BMI and BMI-z decreased over time, and HIIT performed at least twice weekly produced greater reductions than control. Waist-to-hip ratio also differed by group. All HIIT groups improved 20mSRT performance compared with the control. When expressed as 20mSRT-derived estimated VO
