Table 2.

Risk of cardiovascular events or death for non-adherent vs adherent to RAASi hyperkalemia patients after PSM

	Cardiovascular events		Death
	HR [95% CI]	p value	HR [95% CI]	p value
Adherence	1	–	1	–
Nonadherence	1.45 [1.02–2.08]	0.041	2.26 [1.62–3.15]	< 0.001
Age	1.01 [1.00–1.03]	0.032	1.05 [1.04–1.07]	< 0.001
Male gender	1.99 [1.34–2.96]	0.001	1.05 [0.75–1.47]	0.783
Charlson comorbidity index	0.98 [0.88–1.09]	0.687	1.21 [1.11–1.32]	< 0.001
CKD stage	0.80 [0.55–1.14]	0.218	1.10 [0.79–1.53]	0.576

Due to the low sample size, only age, male gender, CCI and CKD stage were considered
