Proximal medial tibial metaphyseal bump-a normal variant.
Article in Pediatric radiology, 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
backgroundSkeletal abnormalities are important to recognize in the workup of physical child abuse. Normal variants can simulate child abuse and cause incorrect diagnosis and management. An osseous protuberance of the proximal medial tibial metaphysis, "the tibial bump," is a normal variant that is important to recognize.
objectiveTo determine the prevalence of a tibial bump in infants undergoing a skeletal survey for a child abuse evaluation. MATERIALS AND
methodsA retrospective study of initial and follow-up child abuse skeletal surveys at a tertiary center was conducted to assess for the presence of a tibial bump on the proximal medial tibial metaphysis. The presence or absence of fracture healing changes around the tibial bump was recorded.
resultsTwenty of two hundred sixty cases showed a tibial bump on the initial skeletal survey, estimating a prevalence of 7.7%. Fourteen of these twenty cases (70%) demonstrated a persistent tibial bump unchanged in appearance on the follow-up skeletal survey. None of the tibial bumps demonstrated findings of a healing fracture on the initial or follow-up skeletal survey. In cases with a tibial bump present, 10 (50%) were bilateral and 10 were unilateral (50%). The mean (median) age of a child with a tibial bump was 3.5 (2.9) months with a range from 1 to 8 months, and there was a statistically significant association between age and the presence of a bump, supporting that this is a finding of infancy (P = 0.04).
conclusionA tibial bump on the proximal medial tibial metaphysis was a relatively common finding in infants undergoing workup for child abuse and not radiographically consistent with a fracture. It is a normal variant and should not be confused with a traumatic finding.
