Selecting effect modifiers among age, SBP, BMI, CRP, and AST.

Covariate	Subgroup	Optimal drug combination	Effect modifier	Covariate	Subgroup	Optimal drug combination	Effect modifier
SBP	Normal	123	Yes	BMI	Normal	123	No
	High	126			Obesity	123
Age	0 - 30	126	Yes	CRP	Normal	12	Yes
	30 - 60	123			High	123
	60 - 80	12		AST	Normal	123	No
	High	123

The combinatorial treatment with the lowest observed failure rate varies across different patient subgroups stratified by the effect modifier.
