Figures & data
Figure 1. Flow chart from the Noble study. As shown, 5 of the 36 centers including patients in the randomized trial assigned the planned registry for non-randomized patients. CABG: coronary artery bypass surgery; PCI: percutaneous coronary intervention; MI: myocardial infarction. *Six received CABG as index treatment and seven received no index treatment. †26 received PCI as index treatment and seven received no index treatment.

Table 3. Mortality at the end of the 3611 day (9.9 years) observation period in patients with low (score table 1 < 6) or high (score table 1 > 5) clinical risk profile.
Figure 2. Kaplan–Meier survival curves for patients treated with PCI or CABG. All patients in the registry are identified in the Norwegian Registry for Public Health (Folkeregisteret) with a complete track of death dates in the population. Censored data (vertical bars) therefore mean observation time for patients still alive at the assessment date of 20 October 2020. The longest recorded observation period was 3611 days or 9.9 years. Log Rank test: p < .001.
