Extended Data Fig. 5: Consultation duration and experience stratified by participant types and study settings.

a, By participant types. b, study settings. Box plots depict patient consultation time across the three trial arms (PreA-only, PreA-human, No-PreA). The center line indicates the median, the box boundaries the first and third quartiles, and the whiskers extend to the most extreme data points within 1.5 × IQR. Dot plots show patient-reported experience metrics (ease of communication, perceived physician attentiveness, interpersonal regard, patient satisfaction, and future acceptability) and physician-reported perceived value on care coordination, with error bars representing standard deviation. Sample sizes for each subgroup are provided in Table 1. We assessed the normality of value distributions and used two-sample t-tests with unequal variances for intergroup comparisons. For significantly skewed dimensions, we employed non-parametric Mann-Whitney U-tests. All tests were two-tailed. The Benjamini-Hochberg adjustment was applied for multiple testing corrections based on the total number of tests.
