Kaplan-Meier curves demonstrating time to first unplanned hospitalization by multimorbidity pattern in older transplant-ineligible veterans newly treated for multiple myeloma in Veterans Affairs. Time to first hospitalization varied across patterns (log-rank 2-sided P < .001). Shaded areas around solid curves represent 95% confidence intervals. Dashed lines represent median time to first hospitalization for each multimorbidity class, as follows: minimal comorbidity = 2.06 years, diabetes and complications = 1.21 years, chronic lung disease = 0.83 years, psychiatric and substance use disorders = 0.72 years, and multisystem impairment = 0.61 years.
