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

Purpose: This study aimed to evaluate the effects of three different crank lengths (165 mm, 170 mm, and 175 mm) on cycling efficiency, sprint performance, and perceived fatigue in high-level amateur road cyclists. Methods: A single-blind, randomized crossover design was employed, involving 28 trained male cyclists who completed three trials, each using a different crank length. Performance metrics, cycling economy (CE) including 20-min cycling under 60 % VO Results: The results indicated significant differences in 60 %VO Conclusion: For high-level amateur road cyclists, using a 165 mm or 170 mm crank reduces subjective fatigue compared to a 175 mm crank, influencing affecting cycling efficiency or sprint performance. These findings help refine crank length recommendations to optimize performance, reduce injury risk, and improve comfort for high-level amateur road cyclists.
