The sex differences in hospitalization and 30-day readmission are attenuated and do not vary by age when stratified by serum albumin. Adjusted incidence rate ratio (IRR) of hospitalization (left) and difference in adjusted probability of readmission within 30 days of discharge (right) comparing women to men by age, stratified by serum albumin. Error bars represent 95% CIs. Hospitalization IRRs and readmission probability adjusted for race, geographic region, calendar year of dialysis initiation, time since initiation of dialysis, insurance, Charlson index, diabetes, and cardiovascular comorbidities, and the interaction of age and race. Pr(30d readmit), Probability of readmission within 30 days of discharge.
