The relationship between cam morphology and hip and groin symptoms and signs in young male football players.
Article in Scandinavian journal of medicine & science in sports, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 papers.
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
backgroundConflicting and limited high-quality prospective data are available on the associations between cam morphology and hip and groin symptoms and range of motion (ROM).
objectivesThis cross-sectional cohort study investigated associations between cam morphology presence, size and duration and symptoms and ROM.
methodsAcademy male football players (n = 49, 17-24 years) were included. Standardized antero-posterior pelvic and frog-leg lateral radiographs were obtained at baseline, 2.5- and 5-year follow-up. The femoral head-neck junction was quantified by: Visual score. Cam morphology (flattening or prominence), large cam (prominence). Alpha angle. Cam morphology (≥60°), large cam (≥78°). Cam morphology duration was defined as long (first present at baseline) or short (only from 2.5- to 5-year follow-up). Current symptoms at 5-year follow-up were assessed using a hip and groin pain question and by the "Hip and Groin Outcome Score" (HAGOS). HAGOS scores were categorized into: most symptoms (≥2 domains in lowest interquartile range [IQR]), least symptoms (≥2 domains in highest IQR). Hip ROM was measured by goniometry at 5-year follow-up.
resultsLarge cam morphology based on visual score was associated with hip and groin pain (23.8% vs. 7.1%, OR: 3.17, CI: [1.15-8.70], P = .026), but not with HAGOS scores. Cam morphology presence, size, and duration were associated with limited flexion of around 6° and/or 3° to 6° for internal rotation.
conclusionCam morphology presence, size, and duration were associated with limited hip flexion and/or internal rotation, but differences might not exceed the minimal clinical important difference. Whether cam morphology results in symptoms is uncertain.
