FIGURE 3.

Estimated prevalence [% (95% CI)] of zinc deficiency with the use of different adjustment approaches in PSC. Zinc deficiency is defined as a plasma or serum zinc concentration <57 µg/dL in the afternoon or <65 µg/dL in the morning (nonfasting) in PSC. Bars within a given survey without a common letter are significantly different, P < 0.05 (adjusted for multiple comparisons). Statistical comparisons were not made with the prevalence of zinc deficiency under the exclusion approach, because the population of PSC is different. Adjustment methods only account for CRP in Ecuador. AGP, α-1-acid glycoprotein; CRP, C-reactive protein; PSC, preschool children.
