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

purposeWe aimed to 1) identify predictors of delayed and nonunion of tibial shaft fractures in patients treated with intramedullary nailing (IMN), including patient demographics and surgical factors, and 2) determine whether the nail/shaft ratio is associated with delayed and nonunion.

methodsThis retrospective, multicenter study included 315 patients with tibial shaft fracture treated with IMN between 2014 and 2019 and excluded patients with insufficient follow-up for 12 months, lost data and inadequate radiographs. Finally, we analyzed 258 patients (184 males; 74 females). Main outcome measurements were delayed union at 6 and nonunion at 12 months after surgery as determined on anteroposterior and lateral radiographs. We extracted the following as risk factors of delayed and nonunion: age, sex, BMI, fracture site, fracture type, injury energy, smoking history, and nail/shaft ratio. We conducted logistic regression analysis to investigate risk factors of delayed and nonunion using these extracted items as explanatory variables.

resultsType C fracture was independently associated with delayed union (odds ratio 2.9, 95% confidential interval: 1.04-8.09, P = 0.04). Nail/shaft ratio was not an independent factor of delayed union. No independent explanatory factors were related to nonunion.

conclusionsType C fractures, which were unstable and fragmented, was associated with delayed union in tibia fractures treated with IMN, whereas nail thickness was not associated with delayed or nonunion fractures.
