1WAZ, weight for age Z score.
2LAZ, Length for age Z score.
3HCZ, weight-for-head circumference z scores.
4p means the p-values calculated by multiple linear regressions for raw model (no adjustment applied), p<0.05 means statistically significant.
5plm means the p-values obtained from multiple linear regressions for model 1, which has been adjusted for city, infant age, and infant sex, p<0.05 means statistically significant.
