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

Background/purpose: Large language models (LLMs), such as GPT-4o and Gemini Advanced, have performed strongly on global medical examinations. However, their capabilities in non-English, dentistry-specific licensing contexts remain unclear. Thus, this study aimed to compare the performance, consistency, and question-generation abilities of GPT-4o and Gemini Advanced in the Korean National Dental Licensing Examination (KNDLE). Materials and methods: This study used 1,401 text-based KNDLE questions from 2019 to 2023 in Korean. Each model responded to the questions in three separate runs. Accuracy and consistency were compared with human answers. The models generated new questions in four subject areas and attempted to solve each other's generated items. Paired t-tests and chi-square tests were conducted. Results: GPT-4o achieved significantly higher average accuracy than Gemini Advanced (81.1 % vs. 76.6 %, Conclusion: GPT-4o outperformed Gemini Advanced in accuracy, consistency, and alignment with its generated content. However, challenges remain in clinical domains and cross-model understanding, highlighting the potential of LLMs as supportive tools for non-English dental education and question generation while emphasizing the persistent need for expert oversight and domain-specific refinement.
