Concordance of surgical treatment with AO/OTA subclassification in intertrochanteric femoral fractures.
Article in Journal of orthopaedic surgery and research, 2026. 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
backgroundThis study aimed to evaluate the association between AO/OTA subclassification and treatment selection in intertrochanteric femur fractures and to determine how closely real-world clinical decisions align with classification-based recommendations.
methodsA retrospective analysis was performed on 474 patients treated for intertrochanteric femur fractures between 2015 and 2020. Fractures were subclassified according to AO/OTA 31-A classification using standard radiographs. Chi-square tests with Cramer's V were used to assess the relationship between fracture groups and treatment modalities. Multinomial logistic regression evaluated predictors of treatment choice, while guideline adherence was analyzed using binary logistic regression. A p value < 0.05 was considered statistically significant.
resultsPFN was the most frequently applied treatment (74.1%), followed by conservative management (13.5%) and DHS (5.7%). Treatment distribution differed significantly among AO/OTA groups (χ
conclusionsAlthough AO/OTA subclassification significantly influences treatment choice, fracture morphology alone is insufficient for determining management. PFN remains preferred across fracture types, while non-operative care is suitable for high-risk patients. Future models should integrate frailty, bone quality, and functional status.
