All intercontinental comparisons except SSAvsNAF, vs. SSAvsEUR, SSAvsSEA, vs. SSAvsOCE, and SSAvsNAM, vs. SSAvsSAM, were statistically significant (p < 0.01) in the ANOVA. AUS, australia; EUR, europe; NAF, north africa; NAM, north america; NEA, northeast asia; OCE, oceania; SAM, south america; SEA, southeast asia; SWA, southwest asia; SSA, Sub-Saharan Africa; SD, standard deviation.
