Fig. 3: HRs for overall mortality based on serial ECG recordings.

Fig. 3

The first row presents data exclusively from a single ECG at baseline examination, illustrating initial risk association. The second row focuses on single ECG from the first follow-up examinations conducted after 5–6 years. The third row includes “Serial ECGs—Consistent Predictions” that showed “Overestimation” in both, baseline and follow-up ECGs. To analyze the influence of serial ECGs, “Follow-up” is compared to “serial ECG,” with both having a follow-up period of up to 16 years w.r.t. mortality data. “Baseline” shows the influence of a longer follow-up period w.r.t. mortality data of up to 21 years in the same individuals.
