Note: CI = confidence interval, NH = nursing home, PH = pediatric hospital, SD = standard deviation, SF-8 = 8-item Short Form Health Survey, SF-36 = 36-item Short Form Health Survey. Bolded values indicate statistically significant results; bolded values with asterisk indicate results that are both statistically and clinically significant. For the SF surveys, minimum differences of 3-5 are generally considered clinically important.54-59
