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

Background: Maturity status varies among adolescents of the same age, making age an unreliable indicator. Although maturity status affects movement patterns, differences in landing force and jump performance among maturity groups remain unclear. Hypothesis/Purpose: This study compared landing force and jump performance during drop vertical jump in adolescent male soccer players based on classifications by maturity status and age. A hypothesis was formulated that landing force would be greater during the period of peak height velocity (PHV) and jump performance higher in the post-PHV group, showing clearer differences than age. Study Design: Cross-sectional study. Methods: Forty-five male soccer players (13.5 ± 0.9 years) were grouped by maturity status (pre-, circa-, and post-PHV), and by age. Landing forces (peak vertical ground reaction force [PVGRF], time to PVGRF, and loading rate) and jump performance (jump height, contact time, reactive strength index [RSI], PVGRF, and power) were measured using a force plate. A one-way analysis of variance was performed to detect group differences. Results: Landing forces showed no significant differences among maturity groups (PVGRF: Conclusion: Maturity status classification detected significant group differences in jump height, RSI, and power, but age classification only detected a significant group difference in jump height. Level of Evidence: 3.
