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

backgroundThe newly developed large language model (LLM) DeepSeek has shown potential for application in other medical fields. However, few systematic studies have assessed its concordance with international expert consensus or compared its performance with leading models such as Gemini 2.0 Pro and ChatGPT-4o in breast cancer. MATERIALS AND

methodsA total of 139 consensus questions from the 19th St. Gallen International Breast Cancer Conference (SG-BCC) were included into analysis. Each model was trained to answer each consensus question five times. The DeepSeek model was compared with the expert panel consensus in terms of concordance rate, robustness of the answers, Pearson correlation coefficient r for non-binary questions, and absolute proportion difference for binary questions. At the same time, a horizontal comparison was made with the previous LLMs Gemini 2.0 Pro and ChatGPT-4o.

resultsThe overall concordance rate between DeepSeek-V3 and the expert panel consensus was 63.31%, and the average answer robustness (i.e., its self-consistency across repeated queries) of DeepSeek-V3 was 86.69%. In addition, DeepSeek-V3 performed similarly to Gemini 2.0 Pro and ChatGPT-4o in terms of concordance rate of the most frequent answers (p = 0.849). In terms of model robustness, there were significant statistical differences among the models (p < 0.001), with DeepSeek-V3 significantly outperforming Gemini 2.0 Pro (p = 0.005) and ChatGPT-4o (p < 0.001).

conclusionsDeepSeek models showed moderate concordance in following the consensus of breast cancer expert panel and showed significant advantages in answer robustness, suggesting that DeepSeek has great application potential in the field of clinical decision-making for breast cancer.
