aRR: relative likelihood that a subject with CHF, compared to a subject without CHF would incur any type of healthcare cost
Note: 1) The upper 1 percentile of costs within each age and sex group and service type were excluded;
2) A total of 185 patients were on dialysis at index or initiated dialysis in the first year post index. These patients were excluded from analysis of secondary clinics costs (61 and 124 had incurred costs in the upper 1 percentile and lower 99%, respectively), and from total costs analysis (94 and 91 had incurred costs in the upper 1 percentile and lower 99%, respectively);
3) All models adjusted for sex, age, SES, AF, MI, non-MI IHD, CVA, TIA, PVD, Diabetes mellitus, hypertension, and CKD (with and without dialysis)
