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

contextLower extremity muscular strength may vary by different sport participation during growth process.

objectiveTo investigate effect of sport participation and growth by comparing strength of the hamstrings, quadriceps, and hamstrings to quadriceps strength ratio (H:Q ratio) between young female figure skaters and soccer players.

designCross-sectional. SETTINGS: Laboratory affiliated with regional sports medicine center.

participantspediatric and adolescent female athletes. PROCEDURES: Isometric hamstrings and quadriceps strength were measured.

main outcome measuresStrength of the hamstrings, quadriceps, and hamstrings to quadriceps strength ratio (H:Q ratio). STATISTICAL ANALYSIS: Effect of sport participation and growth was analyzed through a two-way (two sports: figure skaters and soccer players; three age groups: <12 years, 13-16 years, and >17 years) analysis of covariance.

resultsHamstrings strength was significantly greater in figure skaters than soccer players. Also, hamstring strength of 13-16 years and >17 years was higher compared to <12 years. Additionally, significantly higher H:Q ratio in figure skaters compared to soccer players.

conclusionsThere is effect of growth on hamstrings strength among 13-16 years and >17 years compared to <12 years. Figure skaters showed greater hamstrings strength and H:Q ratio than female soccer players.
