^aCluster membership is defined as ever belonging to the corresponding cluster during hospitalization

^bModels are adjusted for age, sex, body mass index and race/ethnicity

^cP values correspond to Fisher’s exact test for difference in proportions of men and women within each cluster

^dOR significantly less than 1; lower odds of death for patients who belong to this cluster during hospitalization compared to patients who never belong to this cluster

^eOR significantly greater than 1; higher odds of death for patients who belong to this cluster during hospitalization compared to patients who never belonged to this cluster
