^a within-pair difference significant at alpha = 0.001. Prevalence of 0 indicate prevalence less than 0.5%. Mean hemoglobin and % anemia estimates account for complex survey design. SD, skew and kurtosis do not. All tests of between-survey differences are based on complex survey design. BRINDA BR, Biomarkers Reflecting Inflammation and Nutritional Determinants of Anemia project.
