Length-for-age (LAZ), weight-for-length (WLZ) and weight-for-age (WAZ) z scores from birth to 12 months of age by birthweight (A, LAZ; B, WLZ; C, WAZ) and size for gestational age (D, LAZ; E, WLZ; F, WAZ). Values are means and 95% confidence intervals, n = 357. In A, B, and C, square symbols indicate low birthweight; circle symbols indicate non-low birthweight. In D, E, and F, square symbols indicate small-for-gestational age; circle symbols indicate non-small-for-gestational age. Low birthweight was defined as birthweight <2.5kg. Small-for-gestational age was defined as birthweight <10th percentile for gestational age. *P <0.05, ** P <0.01, *** P <0.001 different from low birthweight or small-for-gestational age group.
