Predictive model of delayed union of tibial and fibular fractures based on PGC-1α, NOS, and Runx2.

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
objectivesTo explore the associations between the levels of Peroxisome proliferator-activated receptor γ coactivator 1α (PGC-1α), Nitric oxide synthase (NOS), Runt-related transcription factor 2 (Runx2) and the delayed union of tibiofibular fractures, and to construct and validate a model for predicting the delayed union of tibiofibular fractures.
methodsA total of 351 patients with tibiofibular fractures who were treated in the hospital from January 2022 to June 2024 were selected as the study subjects. They were randomly divided into a training set (n = 246) and a validation set (n = 105) at a ratio of 7:3. Experimental techniques such as ELISA were used to accurately detect the serum of patients, and multiple clinical data of the patients were comprehensively collected. Key influencing factors were screened out by statistical methods, such as univariate analysis and multivariate logistic regression analysis. Plot a nomogram and construct a prediction model, and use evaluation indicators to comprehensively evaluate and validate the model.
resultsIn the training set, 72 cases (29.27%) had delayed union of tibiofibular fracture. Multivariate logistic analysis showed that fracture complexity, time from injury to surgery, levels of PGC-1α, NOS, Runx2, and OPG were independent influencing factors for the delayed union of tibiofibular fractures (all P < 0.05). In the training set and the validation set, the C-index of the nomogram model was 0.760 and 0.711, respectively. The calibration curve showed moderate agreement between the predicted values and the actual values. The results of the Hosmer-Lemeshow test were χ
conclusionsThis study provides a new perspective and method for the assessment of the delayed union of tibiofibular fractures, which is helpful for clinicians to potentially assist in risk stratification and closer follow-up for high-risk patients.
