Ordinal multinomial regression analysis using dentists’ test-positive as dependent variable. For the multivariate analysis the forward stepwise method was used.

	Dentists positive rate
Variables	β	Standard Error	p-value
GNI (>$35,000 a year)	0.72	0.43	0.03
CPR (>10)	1.07	0.24	<0.01
ffp2/N95 (<25 %)	-1.46	0.43	<0.01
Face-to face	0.61	0.35	0.05
PPr (<25%)	0.32	0.21	0.59

GNI= Gross National Income per capita 2019; CPR=Country Positive Rate % to COVID-19;

ffp2= routine use of ffp2/N95 mask; Face-to-face= Face-to-face clinical activity;

PPr=Private Practice rate
