a
Matched patients received a statistical weight: 1 for 1,943 matched intervention patients, 0.957 for 3,552 patients of the control group who were matched to two partners in the intervention group, and 1.914 for 167 control patients for whom only one matching partner could be identified.
b
CHF is principal or secondary diagnosis of the hospitalization.
