Model using the generalized estimating equation log binomial function on a person-period data set with up to 13 person-periods per patient. Model also adjusted for: age, sex, comorbidities (congestive heart failure, diabetes, hypertension, and dementia), SDI, and missed appointment rate. The time since dialysis initiation covariate was time-varying and based on the patient’s time since dialysis initiation as of the start of each person’s period. See Table 3 for the full model and complete P values.
