Prevalence of Pincer Morphology in Early Adolescents From the General Population: A Population-Based Study.
Article in Arthritis care & research, 2025. 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
objectivePincer morphology can lead to femoroacetabular impingement syndrome (FAIS) and may be a modifiable risk factor for hip osteoarthritis (OA). Currently, no studies investigate the prevalence of pincer morphology in early adolescence, which is the period when this bony shape likely develops. The purpose of this study was to estimate the prevalence and birth-assigned sex distribution of pincer morphology in early adolescents from the general population in the Netherlands.
methodsThis study was embedded in the Generation R Study, a population-based prospective cohort in Rotterdam, the Netherlands. Around the age of 13 years, participants underwent high-resolution dual-energy x-ray absorptiometry of their full-body and right hip. The lateral center edge angle (LCEA) was automatically determined based on landmarks outlining the hip contour, and pincer morphology was defined as a LCEA ≥ 40°. The overall and birth-assigned sex-specific prevalence was presented as a percentage with 95% confidence interval (CI).
resultsA total of 3,986 adolescents (median age 13.5 years [2.5th-97.5th percentile: 13.2-14.6]; 46.8% male) were included. The overall prevalence of pincer morphology was 3.1% (95% CI 2.6-3.6). The prevalence in male and female adolescents was 3.0% (95% CI 2.2-3.7) and 3.3% (95% CI 2.5-4.0), respectively.
conclusionAmong early adolescents from the general population in the Netherlands, the estimated prevalence of pincer morphology was 3.1%. Male and female adolescents had a similar prevalence of pincer morphology. These findings could inform the timing of prevention strategies for pincer morphology and potentially reduce the risk of FAIS and hip OA.
