SD = standard deviation; CI = confidence interval; IQR = interquartile range; PROMIS = Patient Reported Outcomes Measurement Information System.
PROMIS measures are scored using a T-score metric, mean=50, SD=10 referenced to the U.S. general population. A 95% CI that excludes the value 50 indicates a statistically significant difference from the general U.S. population mean value.
