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

purposeLarge language models (LLMs) have shown potential in medicine, transforming patient education, clinical decision support, and medical research. However, the effectiveness of LLMs in providing accurate medical information, particularly in non-English languages, remains underexplored. This study aimed to compare the quality of responses generated by ChatGPT and Naver's CLOVA X to cancer-related questions posed in Korean. MATERIALS AND

methodsThe study involved selecting cancer-related questions from the National Cancer Institute and Korean National Cancer Information Center websites. Responses were generated using ChatGPT and CLOVA X, and three oncologists assessed their quality using the Global Quality Score (GQS). The readability of the responses generated by ChatGPT and CLOVA X was calculated using KReaD, an artificial intelligence-based tool designed to objectively assess the complexity of Korean texts and reader comprehension.

resultsThe Wilcoxon test for the GQS score of answers using ChatGPT and CLOVA X showed that there is no statistically significant difference in quality between the two LLMs (

conclusionBoth ChatGPT and CLOVA X answered Korean-language cancer-related questions with no significant difference in overall quality.
