  1. A: significant difference between the VLBW and LBW groups, p < 0.01
  2. B: significant difference between the VLBW and NBW groups, p < 0.01
  3. C: significant difference between the LBW and NBW groups, p < 0.01
  4. Mon: months; HC: head circumference; VLBW:very low birth weight, birth weight < 1500 g; LBW: low birth weight, 1500 g ≤ birth weight < 2500 g; NBW:normal birth weight,2500 ≤ birth weight<4000 g. Catch-up growth: a change in the Z-score > 0.67 between two time points. Chi-square test or Fisher’s exact test was used to analyze
