For the purposes of analyses, timing of core food introduction was coded as: 1 = later (6 – 12 months), 2 = average (5 months), and 3 = earlier (1 – 4 months). Timing of non-core food introduction was coded as: 1 = later (11 – 18 months), 2 = average (9 – 10 months), and 3 = earlier (3 – 8 months)
Adj OR = odds ratio adjusted for all listed variables; 95% CI = 95% confidence interval; 1 denotes the reference group
