Information was missing for weight (54), length (63), and HC (61).
Statistically significant comparisons between IVH 3/shunt versus IVH 3/no shunt are shown. Comparisons between IVH 3/shunt versus no IVH/no shunt were statistically significant for length (z score: P = .02; <10th percentile: P = .04) and for HC (P < .01 for z score and <10th percentile) but not for weight (z score: P = .06; <10th percentile: P = .3).
Statistically significant comparisons between IVH 4/shunt versus IVH 4/no shunt are shown. Comparisons between IVH 4/shunt versus no IVH/no shunt were statistically significant for all outcomes (P < .001 for all).
P ≤ .05,
P ≤ .01,
P ≤ .001 for IVH 3/shunt versus IVH 3/no shunt or for IVH 4/shunt versus IVH 4/no shunt by the χ2 or Wilcoxon test.
