Five year all-cause mortality for the combined cohort (Hypothesis 1 and 2) with increasing E/A ratio in the non-imputed (original) dataset; dotted lines indicate 95% confidence interval. Mortality risk was higher in patients with low (< 0.6) and high (> 1.0) E/A ratio and lowest for those with intermediate E/A ratio (0.6–1.0)
