Annual event rates for primary endpoint in patients with quantitative septal LGE above and below the optimal threshold for each STRM technique (5SD 2.74 %, 3SD 6.63 %, 2SD 10.15 % of LV mass) and patients with and without septal scar by visual assessment. The patients with septal LGE greater than the optimal threshold had a significantly higher annual event rate than those without for all the STRM technique, and it was the most prominent for STRM 5SD technique (3.2 % vs 22.6 %, p < 0.0001). LGE = late gadolinium enhancement, STRM = signal threshold versus reference mean
