Fig. 1: Chronological vs ECG-age.
From: Deep neural network-estimated electrocardiographic age as a mortality predictor
The scatter plots display the relation between the predicted ECG-age and chronological age. The black line is the identity line. The lateral histograms show the distributions of predicted ECG-age and chronological age among patients of the cohorts. a CODE-15% cohort, b ELSA-Brasil cohort, c SaMi-Trop cohort. The mean predicted ECG-age was 52 (s.d. 19), 47 (s.d. 11), 63 (s.d. 14), for CODE-15%, ELSA-Brasil cohort and SaMi-Trop cohort, respectively. The R2 (Pearson correlation) was 0.71 (r = 0.84) in the CODE-15%, 0.32 (r = 0.57) in ELSA-Brasil cohort and 0.35 (r = 0.59) in the SaMi-Trop cohort.
