Figure 2 Survival Related to CoQ₁₀ Concentration and to CoQ₁₀ and NT-proBNP 4-Way Split

(A) Survival related to the best predictive value of mortality for coenzyme Q₁₀ (CoQ₁₀) as determined from the receiver-operator characteristic (ROC) curve (0.73 µmol/l), showing values above (green) and below (blue) this cut-point. Log-rank p < 0.001 for the difference between groups. (B) Kaplan-Meier survival curve for patients with above- and below-median CoQ₁₀ in combination with above- and below-median N-terminal peptide of B-type natriuretic peptide (NT-proBNP). Differences in survival among patient groups are indicated, except where nonsignificant. Medians: CoQ₁₀ = 0.68 µmol/l; NT-proBNP = 238 pmol/l. Values below graphs indicate the number of subjects remaining in the study at each time point.
