Tibial Malalignment Is an Independent Predictor of Nonunion After Intramedullary Nailing of Tibial Shaft Fractures.
Article in Journal of orthopaedic trauma, 2025. 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
objectivesThis study aimed to assess the relationship between postoperative alignment and nonunion in patients with tibial shaft fractures treated with intramedullary nailing.
methods
designRetrospective case-control study.
settingSingle academic trauma center. PATIENTS SELECTION CRITERIA: Adult patients with closed or open tibial shaft fractures (42A-C) treated with intramedullary nailing from 2007 to 2018. OUTCOMES MEASURES AND COMPARISONS: Case patients with nonunion were compared with control patients with radiographic evidence of healing in terms of the postoperative tibial alignment measured in the coronal and sagittal planes.
resultsOf the 192 included patients (median age, 38 years; 76% male), 51 patients had a nonunion, and 141 patients had united fractures and served as the control group. A strong association between postoperative tibial malalignment in 1 plane and nonunion (odds ratio, 3.0; 95% confidence interval, 1.1-8.3; P = 0.03) was demonstrated. This association was even greater for malalignment in both coronal and sagittal planes (odds ratio, 5.7; 95% confidence interval, 2.1-16.1; P < 0.001) after controlling for confounders.
conclusionsAfter controlling for confounding factors, postoperative malalignment in the coronal or sagittal plane was associated with significantly increased odds of tibial shaft nonunion after intramedullary nailing. LEVEL OF EVIDENCE: Prognostic, Level III. See Instructions for Authors for a complete description of levels of evidence.
