Evaluation of surgical recommendation algorithms in hallux valgus cases using ChatGPT models: an artificial intelligence approach based on 50 simulated scenarios.
Article in Acta orthopaedica et traumatologica turcica, 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
objectiveThe integration of large language models (LLMs) into orthopedic surgical decision-making represents a growing area of research. This study aimed to compare the surgical recommendation capabilities of ChatGPT-4.0, ChatGPT-4o, and ChatGPT-5 models in simulated cases of hallux valgus deformity.
methodsA total of 50 simulated cases were constructed using fundamental clinical data related to hallux valgus pathology and were individually submitted to 3 models. For each case, a surgical recommendation and a brief rationale were obtained. The responses were compared based on content alignment, adequacy of justification, and consistency with established surgical algorithms. Additionally, textual outputs were evaluated using DISCERN and multiple readability indices.
resultsAll 3 models demonstrated overall algorithmic consistency. However, the ChatGPT-5 model provided the most context-aware and clinically consistent recommendations, followed by ChatGPT-4o and ChatGPT-4.0. Concordance rates with surgical algorithms were 70% for ChatGPT-4.0, 82% for ChatGPT-4o, and 90% for ChatGPT-5. DISCERN scores were 51, 56, and 62, respectively. ChatGPT-5 also achieved superior performance across readability metrics, including Flesch Reading Ease Score, Simple Measure of Gobbledygook, and Gunning-Fog Index, indicating improved textual clarity and reduced complexity.
conclusionThe ChatGPT-5 model demonstrated the highest contextual accuracy, consistency, and readability in surgical decision support for hallux valgus surgery, highlighting the progressive improvements of newer LLMs. Nonetheless, ChatGPT-4.0 and ChatGPT-4o also exhibited compatibility with surgical algorithms, indicating potential utility in generating patient education and informational content.
