Table 4. Predictors of MACCE in the ACh-negative population by univariable and multivariable Cox regression analysis.

Predictors of MACCE	Univariable analysis		Multivariable analysis
	HR (95% CI)	p-value	HR (95% CI)	p-value
Epicardial coronary diameter reduction ≥90%	3.208 (1.192-8.629)	0.021*	3.132 (1.163-8.433)	0.024*
Dyslipidaemia	0.342 (0.119-0.984)	0.047*	0.350 (0.121-1.007)	0.052
*Indicates statistical significance. All the characteristics shown in Table 1 were tested to predict MACCE at follow-up, although only variables with a p-value<0.05 have been shown in this table. Variables that were significantly (p<0.05) related to MACCE at follow-up on univariable Cox regression analysis were included in the multivariable Cox regression analysis. ACh: acetylcholine; CI: confidence interval; HR: hazard ratio; MACCE: major adverse cardiovascular and cerebrovascular events
