Significant at < 0.05, < 0.01. “−” indicates number was <10 so cell entry suppressed. Comorbidity index: range (0–7). The range of the score of someone to take you to doctor if you needed it: 1: none of the time, 2: a little of the time, 3: some of the time, 4: most of the time, and 5: all of the time.
