Prevalence of Hip Skeletal Deformity in Japanese Male Collegiate Long-Distance Runners.
Article in Sports medicine international open, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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 study aimed to examine whether hip deformity has already developed in Japanese male freshman collegiate long-distance runners and to investigate the association with their sports history.A total of 57 elite freshman collegiate long-distance runners participated. We collected sports history data during adolescence using a questionnaire, and hip images were measured using dual-energy X-ray absorptiometry. Cam morphology was defined based on visual scores of the anterior head-neck junction, classified as follows: (i) normal, (ii) flattening, and (iii) prominence. Pincer morphology was defined as a bony prominence or osteophyte-like protrusion at the acetabular rim.Cam morphology based on visual scores was found in 78 of 114 hips (68.4%; 40 right and 38 left). Pincer morphology based on visual scores was found in 73 of 114 hips (64.0%; 39 right and 34 left). There was no significant association between hip deformity and sports participation history (
