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

backgroundFew studies have investigated the contributing factors for pediatric radial neck fractures. This study aimed to analyze the radiographic and clinical factors that influence the treatment outcomes in pediatric radial neck fracture.

methodsThis retrospective study included the 112 pediatric patients with radial neck fracture. On elbow radiographs, angulation, displacement, and carrying angle were measured, and fractures were classified using the modified Judet classification. Clinical outcomes were assessed using the Flynn criteria based on the elbow ROM and carrying angle. Univariable and multivariable Firth logistic regression analysis was used to assess the risk factors for unsatisfactory clinical outcome.

resultsAccording to the Flynn criteria, 99 (88.4%) and 13 (11.6%) patients had satisfactory (excellent or good) and unsatisfactory (fair or poor) outcomes, respectively. There were statistically significant differences in the initial displacement and follow-up duration between the two groups (p = 0.002 and 0.025, respectively). Multivariable Firth logistic regression analysis showed that initial displacement was the only independent risk factor for unsatisfactory clinical outcomes after pediatric RNF (odds ratio = 1.448, p = 0.002). The cutoff value of displacement for predicting unsatisfactory clinical outcomes was 72% with a 53.9% of sensitivity and an 87.9% of specificity.

conclusionsThis study showed that greater initial displacement was associated with an increased risk of unsatisfactory clinical outcomes in pediatric radial neck fractures. The exploratory 72% displacement threshold may help identify higher-risk patients; however, further validation is required before clinical application.
