Instruction tuning for colorectal histopathology: a multimodal vision-language assistant on human-evaluated data.
Article in Proceedings of SPIE--the International Society for Optical Engineering, 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
Despite the previous research on general-purpose Multimodal Large Language Models (MLLM) and histopathology multimodal chatbots, there has been limited exploration of their applications, particularly concerning colorectal cancer (CRC) histopathology slides. The success demonstrated by Language and Vision Assistant (LLaVA) as an MLLM in the natural image domain suggests its suitability for downstream tuning in histopathology slide analysis. In this study, we present CChat, a novel adaptation of the LLaVA model, to investigate its utility in CRC computational pathology. We accomplish this by fine-tuning LLaVA on a custom human-validated dataset curated from CRC histopathology slides. We also generate a benchmark dataset, to empirically evaluate CChat with other state-of-the-art chatbots, on which our model achieved final BERTScore, BLEU and Rouge-L scores of 93.23, 44.91, and 44.85, respectively, illustrating our methodology's potential for generation of high-quality instruction datasets.
