CCN2 and Schnyder corneal dystrophy: While higher CTGF levels were associated with an increased risk of all-cause mortality (aHR: 6.652, 95% CI: 2.770–15.974, p < 0.001) and CV mortality (aHR: 6.607, 95% CI: 2.262–19.296, p < 0.001), this model did not show a statistically significant increase in risk for sudden cardiac death (SCD) (aHR: 4.397, 95% CI: 0.487–39.722, p = 0.187).
