CPR choice, by experimental condition

	Odds Ratio (95% Confidence Interval)
Experimental condition	CPR, n (%)	Base model	+ imbalanced covariate*	+ significant covariates†
Overall	141 (56)

Aroused, or “hot” emotional manipulation	71 (56)	1.03 (0.63-1.70)	0.96 (0.58-1.59)	0.89 (0.53-1.49)
MD does not attend to emotion	75 (59)	Ref	-	Ref
MD attends to emotion	66 (53)	0.78 (0.47-1.28)	-	0.77 (0.46-1.30)
MD frames CPR as the norm	81 (64)	Ref	-	Ref
MD frames no CPR as the norm	60 (48)	0.52 (0.32-0.87)	-	0.53 (0.32-0.89)

MD frames the CPR decision as the patient’s	71 (56)	1.03 (0.63-1.69)	-	0.98 (0.58-1.64)

MD frames the alternative to CPR as “AND”	61 (49)	0.58 (0.35-0.96)	-	0.59 (0.35-0.99)

DNR – do not resuscitate order, AND – allow natural death, Ref – reference
