Weighted estimates, 95% confidence intervals, and p-values for imputed survey regression models of hemoglobin, ferritin, % transferrin saturation, and transferrin receptor as dependent variables, reproductive variables as independent variables, and ethnicity, survey release year, and other covariat

aThe n for the hemoglobin, ferritin, and % transferrin saturation model is 6603 (all years).
bThe n for the transferrin receptor model is 3295 (survey years 2003–2006 only).
cMean R2 of 50 imputations.
dReference category is white ethnicity.
eReference category is survey release year 1999–2000 (hemoglobin, ferritin, and % transferrin saturation models).
fReference category is survey release year 2003–2004 (transferrin receptor model only).
