a
NC = odds ratio not calculable because of zero cell. For fish consumption, p,0.001 by Fischer's exact test. For visit type, there were no significant differences between groups (p50.13 by Fischer's exact test).
b
Outbreak illness is a case with the same food exposure as at least one other case.
c
Odds of confirmation for each additional day of symptom duration at the time of the call to the poison information center.
OR = odds ratio
CI = confidence interval
ED = emergency department
