3-years readmissions NRI and IDI values of patients with EF ≥ 50, when comparing baseline model to baseline + EF model, comparing baseline model to baseline + EFa model, comparing 15BT model to 15BT + EF model and when comparing 15BT model to 15BT + EFa model.

Patients with EF ≥ 50, assessment for readmissions within 3 years	Baseline + EF	Baseline + EFa	15BT + EF	15BT + EFa

event risk score changes (×10−3)	1.398	6.026	0.027	5.458
non event risk score changes (×10−3)	0.230	−0.408	0.607	0.242
NRI	0.065	0.352	0.113	0.297
proportion of patient with increased risk score in event group (>50% indicates improvement)	58.4%	70.6%	63.7%	68.1%
proportion of patient with decreased risk score in non-event group (>50% indicates improvement)	48.1%	64.7%	47.6%	61.6%
