Linear radiographic measurements of the calcaneus in pediatric population using lateral radiographs of the foot.
Article in Skeletal radiology, 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
objectiveThis study aims to provide normative data on normal linear measurements of the lateral calcaneus surface in pediatric subjects aged 2 and 18 years, analyzing variations across age groups and genders using lateral foot radiographs to aid in assessing calcaneal disorders.
methodsA total of 716 lateral foot radiographs (381 males and 335 females) with a mean age of 8.99 years (range, 2-17) were included. Subjects were divided into five age groups (2-4, 5-7, 8-10, 11-13, and 14-17) to assess calcaneal morphometric changes with growth. Pediatric patients aged 2-18 years with healthy, weight-bearing lateral foot radiographs were included. Exclusion criteria were hindfoot surgery, calcaneal fractures, foot deformities, and poor image quality. Six linear calcaneal measurements (maximum length (MAXL), maximum height (MAXH), minimum height (MINH), load arm length (LAL), body height (BH), and cuboidal facet height (CFH)) were obtained from the radiographs for analysis.
resultsMales showed larger calcaneal measurements than females after the age of 7, with significant differences between age groups (p < 0.001). The highest mean values were observed in the 14-17 age group, while the lowest were in the 2-4 age group. Statistically significant gender-related size differences were found for most parameters, with notable differences in CFH, LAL, and MAXL measurements.
conclusionsThis study provides the largest pediatric sample to date on calcaneal morphometric variations, showing significant age- and sex-related differences in calcaneal dimensions. Notably, after the age of 10, male subjects exhibited significantly greater calcaneal length and height compared to females.
