Baseline characteristics as effect modifier factors between the association of combined healthy lifestyle factors and CVD reduction from the univariate and multivariate meta-regression model according to the age of study participants at baseline.

	Slope	95% CI		τ2 (%)	I2 (%)	p value
Univariate	0.01	0.002	0.03	1.2	18.73	0.028
Multivariate*	0.01	< 0.001	0.03	1.61	22.14	0.042

Multivariate model adjusted with sex.

τ²: the variance of the true effect sizes QM statistic and its p value show whether the moderator is statistically significant in explaining heterogeneity.
