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

BACKGROUND AND

objectivesLarge language models (LLMs) show promise for clinical decision support but remain vulnerable to factual errors. Retrieval-augmented generation (RAG) mitigates this limitation by grounding outputs in authoritative domain knowledge. Therapeutic plasma exchange (TPE) requires consistent, guideline-driven decisions based on the 2023 American Society for Apheresis (ASFA) recommendations. This study aimed to evaluate whether an RAG-based framework could improve accuracy, reliability and standardization of decision support for TPE, compared to conventional LLMs. MATERIALS AND

methodsWe built a hybrid RAG pipeline combining BAAI/bge-base-en-v1.5 embeddings with Chroma and BM25, coupled with structured prompts that encode ASFA categories and grades, Health Insurance Review and Assessment (HIRA) service criteria, and plasma volume computation rules. Thirty de-identified real-world consultation cases were converted into standardized queries. Across six RAG and three non-RAG generative pre-trained transformer (GPT)-series model configurations, each case was answered five times (1,350 outputs). Performance was assessed by item-level accuracy for six elements (diagnosis, ASFA category, grade, insurance applicability, plasma volume, and replacement fluid) and reproducibility on 14 disease-name prompts. Response time and output length were also analyzed.

resultsRAG configurations consistently outperformed non-RAG baselines across items, with the largest gains in plasma-volume calculation and ASFA classification. Reproducibility was markedly higher with RAG across repeated runs. Among all configurations, RAG GPT-4.1-mini showed the most balanced and superior performance, delivering high accuracy with low latency.

conclusionA guideline-grounded RAG approach substantially enhances the accuracy, stability and standardization of TPE consultation compared with conventional LLMs. This RAG-TPE framework demonstrates the feasibility of reliable, clinically oriented decision support in transfusion medicine, warranting further evaluation in prospective clinical workflows.
