2. Fig 1
LOESS regression comparing donor age in years to 10-year all-cause mortality for transplant recipients more than age 60 years. The LOESS is a local regression analysis of nonparametric data to smooth datapoints and define local relationships. Blue symbols indicate LOESS scatterplot model; red line indicates predicted univariate regression; shading represents 95% confidence interval. The estimated inflection point in donor age above which advanced aged recipients (age more than 60 years) incurred increased risk is identified by the red arrow. (CI = confidence interval.)

Kaplan-Meier 5-year survival curves for recipients aged 60 years and more stratified by use of younger age donor (less than 50 years [solid line]) compared with advanced age donor (50 years or more [broken line]). Five-year survival was significantly lower among recipients who received an advanced age heart compared with those receiving a younger heart (67% versus 73%, respectively; log rank p < 0.001).
