Fig. 2From: Impact of cardiovascular involvement on the clinical course of paediatric mitochondrial disordersKaplan Meier survival analysis (a) showing impaired survival (due to all-cause mortality) in patients with cardiovascular involvement (red line) and without CVI involvement (blue line) (p < 0.01). Time zero is defined as time at diagnosis of metabolic disorder. The bends display the 95% confidence interval (CI). A second curve (b) concerning MACE-free survival limited to the subgroup of CVI patients is reported in the bottomBack to article page
