*Compared with children with minimal change in HAZ (±0.25Z). HAZ difference is the difference between HAZ at month 12 and at study enrolment.
†Gestational age <37 weeks. Relative risk ratios are computed using multinomial logistic regression with minimal HAZ change (−0.25 to 0.25Z) as the reference and adjusted for regression to the mean. All the factors examined in the multivariate multinomial logistic regression are reported on univariate analysis (online supplementary table 5). Here only factors with a p value <0.05 are presented; p values are from multivariable multinomial logistic regression.
HAZ, height/length-for-age z-score; RRR, relative risk ratio.
