  • CD, celiac disease; CI, confidence interval; OR, odds ratio.

  • a Self-reported symptoms present often or always during the past 6 months.

  • b Internal nonresponses for non-CD children ranged from n = 126 to n = 285; for CD cases they ranged from n = 1 to n = 7. Proportions were calculated by using the total number of responses for each item as the denominator in the different groups. Thus, internal nonresponses were excluded for each item.

  • c OR of being a screening-detected CD case if symptom(s) present compared with if symptom(s) not present (with 95% CI) calculated by logistic regression, adjusted for gender.

  • d Having ≥1 of the symptom(s) listed above.
