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

backgroundPatients with T1 colorectal cancer (CRC) often show poor adherence to guideline-recommended treatment strategies after endoscopic resection. To address this challenge and improve clinical decision-making, this study aims to compare the accuracy of surgical management recommendations between large language models (LLMs) and clinicians.

methodsThis retrospective study enrolled 202 patients with T1 CRC who underwent endoscopic resection at three hospitals. We compared the decision-making accuracy of two representative LLMs (ChatGPT-4o and DeepSeek) with that of 29 clinicians in determining whether additional surgery was required after endoscopic resection of T1 CRC. To optimize the inputs for the LLMs, we applied a prompt-engineering strategy that combined role prompting, in-context learning, and few-shot learning.

resultsIn clinical practice, we found that the guideline adherence rate after endoscopic resection for T1 CRC was below 80%. We analyzed the pathology reports of 200 patients with T1 CRC, and the results showed that both ChatGPT-4o and DeepSeek significantly outperformed clinical physicians. Subgroup analyses demonstrated that LLMs outperformed doctors regardless of years of experience or professional background. Additionally, the use of Chinese or English input had no significant impact on the performance of the LLMs.

conclusionThis study highlights the potential of LLMs to improve guideline adherence in the post-endoscopic resection management of T1 CRC.
