Controlling for sex, age, age square, days of inpatient care, and days square. “Ref” is the reference category. The value to the right of the variable name shows whether the variables have made a significant contribution to the model. Results in bold have . RR: relative risk. RR > 1.0 means higher likelihood of dying.
