Age-dependent prevalence of the Notch of Harty (pseudolesion of the tibial plafond) in children, adolescents, and young adults.

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
objectivesThe notch of Harty (NOH) is a pseudolesion located at the distal tibial plafond that can mimic a clinically significant osteochondral lesion. Reported prevalence in an adult population ranged between 25% and 45%, but the prevalence in younger age groups is unknown. In this study, we assessed the age-dependent prevalence of the NOH in a young population to investigate potential remodeling over time. MATERIALS AND
methodsA retrospective analysis of a single-center database included 895 ankle MRIs of patients aged 6-25 years between 2018 and 2022. Cases with significant artifacts or pathological conditions were excluded. The NOH was categorized into types 1 (fluid-filled) and 2 (cartilage-filled), and measurements were taken for mediolateral, craniocaudal, and anteroposterior dimensions. Logistic and linear regression models with restricted cubic splines assessed age-related trends. Radiographic sensitivity for NOH detection was evaluated in 252 radiographs with MRI-confirmed NOH as a secondary endpoint.
resultsThe overall prevalence of NOH in this study population was 47.1% (14.9% type 1 and 31.6% type 2). Type 1 prevalence peaked at age 8 and declined into adulthood, while type 2 prevalence peaked at age 14 and stabilized through adolescence. The NOH size increased with age until 16 years and subsequently decreased. Radiographic sensitivity for detecting NOH was 51.2%.
conclusionThe NOH is more common in younger individuals, with prevalence and size decreasing with age. This supports its classification as a developmental variant characterized by age-related remodeling. CRITICAL RELEVANCE STATEMENT: This study provides novel insights into the age-dependent prevalence and remodeling of the NOH, enhancing diagnostic precision and improving differentiation between developmental variants and pathological findings in clinical radiology. KEY POINTS: The study investigates the age-dependent prevalence of the NOH. Results show developmental remodeling patterns with prevalence peaking in younger individuals. Data support the theory of NOH being a developmental variant.
