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: Large Language Models (LLMs) hold substantial potential in medical education. In our previous work, we evaluated the performance of DeepSeek-R1 and ChatGPT-4o on the Chinese National Medical Licensing Examination (CNMLE). Following performance upgrades in December 2025, DeepSeek-V3.2 and ChatGPT-5.2 were released. This study aimed to longitudinally assess the performance evolution of DeepSeek (R1 vs. V3.2) and ChatGPT (4o vs. 5.2) using the 2024 CNMLE as a baseline and to explore their performance on the 2025 CNMLE. Methods: We tested DeepSeek-V3.2 and ChatGPT-5.2 on 600 multiple-choice questions from the written part of the 2024 CNMLE, and compared the results with historical data from DeepSeek-R1 and ChatGPT-4o. The questions consisted of 4 units and were divided into low-difficulty and high-difficulty groups according to different difficulty levels. Additionally, the two latest LLMs were assessed on 600 questions from the written part of the 2025 CNMLE. Results: In the 2024 CNMLE, overall accuracy for the DeepSeek series (R1 vs. V3.2: 92.0% vs. 91.0%) and ChatGPT series (4o vs. 5.2: 87.2% vs. 89.3%) showed no significant differences (all Conclusion: Benchmarked against the 2024 CNMLE, iterative updates did not yield significant performance gains for either LLM series. However, DeepSeek-V3.2 demonstrated a performance advantage on the 2025 CNMLE.
