Figure 4 Difference in fetal growth SD score during pregnancy for intermediate and positive anti-tTG levels relative to mothers with negative anti-tTG levels (n = 7046; P = .02 for overall difference in growth curves between positive and intermediate levels relative to negative anti-tTG levels assessed by the F test; shaded area represents 95% CI; dashed line represents the reference group: negative anti-tTG).
