Models* | Birth weight (z score)regression coefficient(95% CI) | Early weight gain(z score) regression coefficient (95% CI) | Late weight gain(z score) regression coefficient (95% CI) | R^{2} |
---|---|---|---|---|

*Models: univariable models include only one of the three variables, that is, birth weight, early or late weight gain z scores; bivariable models: model 1 includes birth weight and early weight gain z scores, model 2 includes early and late weight gain z scores, and model 3 includes birth weight and late weight gain z scores; multivariable model includes all three variables in the model, that is, birth weight, and early and late weight gain z scores. Early weight gain: change in z score for weight between birth and 6 weeks; late weight gain: change in z score for weight between 6 weeks and 18 months. | ||||
