Table 4. Random effect meta-regression estimates of systolic blood pressure for panethnicity, gender and their interaction.

Variables	Point Estimate	95% CIs	p-value	Multiplicity adjusted p-value
Panethnicity (SSA vs. SA)	8.014	4.369 to 11.660	<0.001	<0.001
Gender (Women vs. Men)	1.618	-1.762 to 4.998	0.348	0.650
Interaction Term
Panethnicity x Gender	0.860	-4.529 to 6.249	0.755	0.980

SSA = Sub-Saharan Africans; SA = South Asians; EU = Europeans. Systolic blood pressure Model (number of comparisons = 80): Intercept: -4.5857 mmHg (-6.862 to -2.310; p<0.001); Proportion of between-study variance explained (Adjusted R-squared) = 34.45%; Joint test for all covariates F = 13.34, p<0.0001
