Shaping AI in Pelvic Floor Physiotherapy: The Impact of Role-Play Prompting on ChatGPT Response Quality.
Article in International urogynecology journal, 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
introduction and hypothesisPelvic floor physiotherapy (PFP) is a highly specialized field requiring complex and multidisiplinary clinical reasoning. While large language models (LLMs) are increasingly being utilized to support clinical education and decision-making in this domain, the relevance, accuracy, and comprehensiveness of their outputs vary significantly depending on prompt engineering. The aim of this study was to examine the impact of persona-based role-play prompting on the quality of ChatGPT responses to clinical questions in PFP.
methodsTwenty-one open-ended clinical questions covering assessment and management of common pelvic floor dysfunctions were presented to ChatGPT (GPT-4.1) under two conditions: (1) a neutral prompt and (2) a role-play prompt instructing the model to respond as an experienced pelvic floor physiotherapist. Two independent physiotherapists rated all responses across four domains-relevance, accuracy, comprehensiveness, and clarity-using a five-point rubric.
resultsPersona-based prompting significantly improved response quality across all domains (p < 0.001). The largest enhancement was observed in comprehensiveness (mean difference; 1.45), followed by relevance, accuracy, and clarity (mean difference; 1.12, 0.88, and 1.48, respectively). Effect sizes were large to very large (Cohen's d; 1.66-2.11). Inter-rater reliability ranged from moderate to excellent (ICC; 0.61-0.81).
conclusionsPersona-based role-play prompting markedly enhances the quality of LLM-generated responses in PFP. For clinicians, educators, and students, adopting structured prompts will substantially improve output quality; however, because accuracy remains imperfect, all generated responses still require careful professional oversight.
