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
objectivesThis study aimed to develop a custom GPT-based, knowledge-guided documentation support system that drafts emergency department (ED) interdepartmental consultation requests from minimal free-text input and evaluate its feasibility, usability, and workflow integration.
methodsThe system generates a patient summary, recommended consulting department, structured consultation draft, and clinical reference notes from brief natural language input, including age, chief concern, and key findings. Two public AI Hub datasets, the Essential Medical Knowledge Dataset (Dataset No. 71875) and the Specialized Medical Knowledge Dataset (Dataset No. 71874), were used to guide prompt construction and constrain output structure rather than for model training. Department recommendation concordance was assessed using 22 de-identified ED consultation scenarios purposively selected across multiple specialties. The documented department was removed from the input and compared with the system's recommendation. A post-use survey of 10 emergency physicians and residents assessed workflow utility, clinical appropriateness, usability, reflection of relevant information, perceived patient safety, adoption intention, and editing requirements using 5-point Likert scales.
resultsIn the 22-case pilot set, the system's recommended department aligned with the historically documented department in all cases under controlled conditions. Given the small sample size and study design, this finding represents preliminary evidence of workflow alignment rather than definitive validation of clinical performance.
conclusionsThe proposed system demonstrates the feasibility of large language modelenabled documentation support for generating standardized ED consultation requests, potentially reducing documentation burden. The system is intended to support, not replace, clinical decision-making, and clinician review remains essential. With further validation, this approach may be adaptable to other clinical referral contexts.
