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
backgroundFemoral fractures in children are uncommon and are usually trauma-related; however, some occur secondary to underlying bone pathology. Early differentiation between traumatic and pathological fractures is essential to avoid delayed diagnosis. This study aimed to identify clinical predictors associated with pathological femoral fractures in children. MATERIAL AND
methodsIn this retrospective single-center comparative study, 432 pediatric patients (0-17 years) with femoral fractures were included. These fractures were classified as traumatic (n = 386, 89.4%; treated between 2011 and 2023) or pathological (n = 46, 10.6%; treated between 2002 and 2021) on the basis of radiological findings, advanced imaging, or histopathological confirmation. Demographic, anatomical, and injury-related variables were compared between the two groups using Mann-Whitney U or chi square tests.
resultsPatients with pathological fractures tended to be older (10.1 ± 4.3 years versus 8.3 ± 5.9 years, p = 0.090) and age-group distribution differed significantly between the two groups (p < 0.001). Traumatic fractures showed a bimodal age distribution, whereas pathological fractures followed a unimodal pattern. Both groups most commonly sustained diaphyseal fractures (58.7% pathological versus 59.8% traumatic). Low-energy trauma mechanisms were significantly more common in pathological fractures (78.9% versus 49.5%, p = 0.001).
conclusionsPathological femoral fractures in children differ from traumatic fractures with respect to age distribution, anatomical location, and injury mechanism. They are more likely to occur following low-energy trauma and demonstrate a different age distribution to traumatic fractures. Careful assessment of patient age, fracture location, and trauma mechanism may aid in the early identification of underlying bone pathology and support appropriate diagnostic evaluation.
