Maternal depression at wave j

exp(ν_{1}) = 1.67

exp(ω_{1}) = 1.61

exp(ν_{1}) = 2.80

exp(ω_{1}) = 2.70

BMI for age zscores at wave j + 1

exp(ν_{2}) = 1.64

exp(ω_{2}) = 1.58

exp(ν_{2}) = 2.60

exp(ω_{2}) = 2.50

 Abbreviations: BMI, body mass index; exp., exponential; MAR, missing at random
 ^{a}Odds ratio for MAR (Strong) = square of the Odds ratio for MAR (Weak)
 ^{b}Models A and B represent the logistic regression models used to generate missingness in maternal smoking from waves 1–5 under MAR, in all subsequent waves and intermittently respectively
