^a,bDifferent superscripts within the same column denote significant difference between NCD status (p < 0.05) for each blood chemistry. The group sizes are unequal. Type I error levels might occur for the ANOVA

^{A, B} Different superscripts within the same row denote significant difference between household income levels (p < 0.05) for each blood chemistry. The group sizes are unequal. Type I error levels might occur for the ANOVA
