Impact of AI-Augmented informed consent on preoperative anxiety and patient understanding: A prospective Observational Study.
Article in Digital health. 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
Objective: This study evaluated the clinical integration of a large language model (LLM) as a supportive communication tool within the preoperative informed consent pathway. Methods: Participants completed the State-Trait Anxiety Inventory (STAI)-1, STAI-2, and Amsterdam Preoperative Anxiety and Information Scale (APAIS) scales after undergoing both the standard informed consent process and the subsequent ChatGPT consultation. Additionally, they completed a five-item questionnaire to assess their experience with the digital consultation. Anxiety scores were statistically compared before and after the AI consultation. Patient satisfaction regarding the digital consultation process was analyzed. Additionally, ChatGPT's responses to the eleven most frequently asked questions were evaluated by three independent urologists in terms of accuracy, comprehensibility, and appropriateness. Results: Anxiety scores decreased significantly. STAI-1 decreased by 3.2 points and STAI-2 by 1.3 points (both p<0.001). ROC analysis identified minimal clinically significant difference (MCID) thresholds of 1.5 for STAI-1 and 0.5 for STAI-2, indicating that these reductions were clinically significant. In contrast, APAIS scores decreased by 0.89 points (p < 0.001), but the ROC analysis was not significant (AUC = 0.559, p = 0.327), suggesting limited clinical relevance. Subgroup analyses showed that reductions in STAI scores generally exceeded the MCID thresholds, whereas APAIS changes did not consistently achieve clinical meaningfulness. Most participants reported that the ChatGPT consultation contributed to their understanding of the surgery (68%). Conclusion: LLM-assisted consultation may serve as a scalable adjunct to clinician-led consent by enhancing perioperative communication and reducing situational anxiety, while requiring continued clinical oversight for safe implementation.
