Effect of dystrophin on survival, heart function, and age at spinal fusion surgery. Kaplan–Meier analysis compares survival (A), and ages at spinal fusion surgery (B), left ventricular ejection fraction (LVEF) < 55% (C), and LVEF < 30% (D) between groups A, B, and C. Subsequent pairwise comparisons were used with Bonferroni correction for multiple comparisons. Probability values are shown on the right side of the diagram. CI = confidence interval; NS = non‐significant.
