Less than or greater than P values are reported when there are no pairwise comparisons, and exact P values are reported when there are pairwise comparisons. Controlling for race and/or ethnicity, parent highest education, family affluence, urbanicity, current residence, and sex. N was the total number of participants who had valid values for blackout in the corresponding wave. W1 to W3: 10th grade to 12th grade; W4 to W7: 1 to 4 y after high school. aOR, adjusted odds ratio; CI, confidence interval.
Exact CI upper limit ranged from 0.98 to 0.99.
