borderline significanceP = 0.05
On Cox regression, LVH showed borderline significance for independent association with all-cause mortality (hazard ratio 1.57, 95% CI 1.01–2.44, P = 0.05) after adjustment for age (predictive of death with hazard ratio 1.09, 95% CI 1.07–1.11, P < 0.005) and sex (predictive of death with hazard ratio 1.68, 95% CI 1.19–2.38, P < 0.005) (Fig. 1 ).
