Benchmarking multimodal large language models for medicinal plant identification.
Article in Frontiers in plant science, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
With the rapid advancement of artificial intelligence technology, large language models (LLMs) have shown considerable potential in the medical field. This study systematically evaluated the performance of five multimodal LLMs, including GPT-4o, Llama4Scout, Gemma3-27B, Qwen3-VL235B, and DeepSeek-VL2, in medicinal plant image recognition tasks. We selected 200 medicinal plant images from a privately copyrighted dataset and tested the models using a four-choice format to evaluate their recognition accuracy. Results indicate that Qwen3-VL-235B demonstrated the highest accuracy at 90.50%, outperforming other models. GPT-4o ranked second at 85.00%, while Gemma3-27B, Llama4Scout, and DeepSeek-VL2 achieved 65.50%, 58.50%, and 58.00%, respectively. These findings indicate that multimodal LLMs hold promising potential for medicinal plant recognition, yet further optimization for specific domains is required to enhance accuracy.
