1 · What the graph read from it

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.

2 · The registry

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

backgroundOsteochondroma is the most common benign bone tumor in childhood. Although most lesions are asymptomatic, surgical treatment is indicated in patients with pain, mechanical symptoms, cosmetic concerns, restricted range of motion, or neurovascular compression. This study evaluated the clinical characteristics and surgical outcomes of osteochondromas in children and adolescents treated at a single tertiary pediatric surgery center.

methodsThis retrospective study included 75 pediatric patients who underwent surgical excision of osteochondroma between January 2015 and January 2026. Demographic, clinical, radiological, operative, histopathological, and follow-up data were analyzed. Lesion-related variables were assessed at the level of individual exostoses. The primary outcome was surgical treatment outcome, while secondary outcomes included lesion localization, symptoms, hospital stay, postoperative complications, recurrence, and associations between clinical and morphological variables.

resultsA total of 75 patients with 76 solitary osteochondromas were included. The median age was 13 years, and 64.0% of patients were male. Most lesions were located distally (73.7%), with the femur being the most common site (48.7%), followed by the tibia (22.4%). Pain was the most frequent symptom, present in 63.2% of exostoses, followed by cosmetic concern in 32.9%. Standard radiography was used in nearly all cases (98.7%). Radiographic measurements significantly underestimated lesion size compared with intraoperative measurements, with median diameters of 3.0 cm and 4.0 cm, respectively (

conclusionsSurgical excision of symptomatic pediatric osteochondromas was associated with favorable postoperative outcomes, a low complication rate, and no observed recurrence during follow-up. Standard radiography correlates well with intraoperative findings but may underestimate true lesion size, likely due to limited visualization of the cartilaginous cap. Symptom development appears multifactorial and cannot be reliably predicted by lesion size or location alone.
