Comparison of the cumulative survival rate between three patient groups: with CAD, without CAD, and without MPI screening. a Patients without CAD by MPI screening showed a significantly higher survival rate for all-cause mortality (blue line) compared with patients without screening (red line) (p < 0.001, log-rank test). The survival curve for the patients with CAD (dotted blue line) depicts almost the same pattern as the patients without CAD (blue line) until the sixth year of the follow-up period; then, the curve steeply drops to the level of the patients without screening (red line) at 10 years. b A significantly higher survival rate for cardiac death was also observed in patients without CAD by MPI screening (blue line) than in patients without screening (red line) (p = 0.009, log-rank test). Similar to the curves for all-cause mortality, the survival curve for the patients with CAD (dotted blue line) shows almost the same pattern as the patients without CAD (blue line) until the sixth year of the follow-up period; then, the curve steeply drops to below the level of the patients without screening (red line) at 10 years
