Table 1 provides demographic, medical cost and utilization, and morbidity patterns of the matched HBPC participant and control samples. The samples demonstrate balance for covariates explicitly matched upon (age; total medical cost; Alzheimer’s disease or CMI; CHD; CVD; CHF; diabetes; COPD) as well as those not (sex; RX, IP and OP costs; arthritis)
