  1. 1. SEM, standard error of the mean
  2. 2. t-test was used to compute probabilities for comparisons of mean age and mean body mass index between study groups.
  3. 3. Chi square test was used to compute the probability for comparison of the distribution of sex between cases and controls.
  4. 4. Fisher's exact test was used to compute the probability for comparison of the distribution of race between the study groups, and was based on Blacks and Whites only.
