  1. aAKI: acute kidney injury; HR: hazard ratio. Model 1: Adjusted for age, sex and propensity score.
  2. Model 2: Adjusted for age, sex, propensity score, ICU admission, admission frequency, Charlson Comorbidity Index score, comorbidities before index hospitalization (cerebrovascular disease, dementia, chronic obstructive pulmonary disease, hemiplegia and metastatic tumor) and respiratory and hematologic comorbidities during index hospitalization. Model 3: Adjusted for age, sex, propensity score, admission frequency, Charlson Comorbidity Index score, comorbidities before index hospitalization (peptic ulcer and diabetes mellitus) and cardiovascular and respiratory comorbidities during index hospitalization. Model 4: Model 2 adjusted with subsequent advanced CKD after hospital discharge as a time-varying covariate. Advanced CKD is defined as patients with serum creatinine levels above 6 mg/dl and a concomitant erythropoiesis-stimulating agent prescription.
