Sex differences in hospitalization and 30-day readmissions vary by age in patients undergoing thrice-weekly hemodialysis. Adjusted incidence rate ratios (IRRs) of hospitalization (left) and difference in adjusted probability of readmission within 30 days of discharge (right), comparing women to men by age. 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 comorbidity index, diabetes, and cardiovascular comorbidities, and the interaction of age and race.
