Supplementary Fig. 2 Path diagram showing the relationship between physician-patient communication, patient satisfaction with treatment decision-making, and patient trust in physicians by categorical variables of patient background (multi-population simultaneous analysis). (a) By PRO2 remission and non-remission. GFI = 0.880, AGFI = 0.817, RMSEA = 0.101. (b) By the time spent with the physician when deciding on treatment. GFI = 0.857, AGFI
= 0.782, RMSEA = 0.105. (c) By the patient decision-making preference scale score. The patient decision-making preference scale was stratified by median. GFI = 0.877, AGFI = 0.814, RMSEA
= 0.099. Values represent standardized path coefficients that indicate the degree of relationship between variables.
