Comparative Analysis of Large Language Models in Dermatological Diagnosis: An Evaluation of Diagnostic Accuracy.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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.
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 diagnostic process in dermatology often hinges on visual recognition and clinical pattern matching, making it an attractive field for the application of artificial intelligence (AI). Large language models (LLMs) like ChatGPT-4o, Claude 3.7 Sonnet, and Gemini 2.0 Flash offer new possibilities for augmenting diagnostic reasoning, particularly in rare or diagnostically challenging cases. This study evaluates and compares the diagnostic capabilities of these LLMs based solely on clinical presentations extracted from rare dermatological case reports. METHODOLOGY: Fifteen published case reports of rare dermatological conditions were retrospectively selected. Key clinical features, excluding laboratory or histopathological findings, were input into each of the three LLMs using standardized prompts. Each model produced a most probable diagnosis and a list of differential diagnoses. The outputs were evaluated for top-match accuracy and whether the correct diagnosis was included in the differential list. Performance was analyzed descriptively, with visual aids (heatmaps, bar charts) illustrating comparative outcomes.
resultsChatGPT-4o and Claude 3.7 Sonnet each correctly identified the top diagnosis in 10 (66.7%) out of 15 cases, compared to 8 (53.3%) out of 15 for Gemini 2.0 Flash. When differential-only matches were included, both ChatGPT-4o and Claude 3.7 achieved a total coverage of 86.7%, while Gemini 2.0 reached 60.0%. Notably, all models failed to identify certain diagnoses, including blastic plasmacytoid dendritic cell neoplasm and amelanotic melanoma, underscoring the potential risks associated with plausible but incorrect outputs.
conclusionsThis study demonstrates that ChatGPT-4o and Claude 3.7 Sonnet show promising diagnostic potential in rare dermatologic cases, outperforming Gemini 2.0 Flash in both accuracy and diagnostic breadth. While LLMs may assist in clinical reasoning, particularly in settings with limited dermatology expertise, they should be used as adjunctive tools, not substitutes, for clinician judgment. Further refinement, validation, and integration into clinical workflows are warranted.
