Comparison of raw and adjusted correlation coefficients r for the SF36 and its two major subcategories (physical health and mental health) against hospitalization data and pertinent clinical, laboratory, and demographic variables. Case-mix adjusted correlation coefficients (controlled for age, race, gender, and underlying renal disease) are indicated in parentheses.
