  1. a Percentage values for pregnancy outcomes in 1991 or later are derived from N = 1448 pregnancies in Gulf War veterans and N = 1555 pregnancies in the comparison group.
  2. b Odds ratios are for miscarriages/stillbirths combined, or terminations, compared to live births. Odds ratios were obtained by polytomous logistic regression adjusting for age, rank, service type, education, marital status, smoking and alcohol.
  3. c CIs are adjusted for clustering of multiple pregnancies within individuals.
  4. d These percentages are derived from N = 885 live births for Gulf War veterans and N = 936 live births for the comparison group for whom birth weight was provided.
  5. e These percentages are derived from N = 978 live births for Gulf War veterans and N = 997 live births for the comparison group for whom duration of pregnancy was provided.
  6. f Standard errors were adjusted for clustering of multiple births within the same individual.
  7. g Due to the small numbers of events, the odds ratio was not adjusted for confounders and clustering. The associated 95% CI was adjusted for clustering.
