Values are expressed in median [IQR] unless otherwise indicated. Values in bold are statistically significant. IPC scores range from 1 to 5.
↵^aLower score is better.
↵^bSubdomains of Hurried communication, as reflected by responses to the question, “How often did doctors use words that were hard to understand?” Score ranges from 1 to 5, with higher scores indicating perceiving providers use more difficult words.
↵^cHigher score is better.
↵^dPROMIS short forms: 50 is reference population mean, 5 is clinically significant difference; higher scores are better for self-efficacy, social function, and physical function, but lower scores are better for anxiety, depression, fatigue, sleep disturbance, and pain interference.
