Figure 1 Kaplan–Meier estimated survival function of overall mortality for male (blue) and female (red) patients who received ITA (solid) and SVG (dash) grafts along with US Department of Health and Human Services life expectancy (did extend 16 years) for men and women aged 80 years. The biennial count of patients remaining in each strata is provided as an insert table. Female patients who received ITAs (solid red, 5 years: 70%, 10 years: 35%) had a survival advantage (P = 9.9987) over female patients who did not (SVGs) (dash red, 5 years: 63%, 10-years: 21%). In contrast, male patients who received ITAs (solid blue, 5 years: 65%, 10 years: 29%) did not have a statistically significant survival advantage (P = .2385) over male patients who received SVGs (dash blue, 5 years: 69%, 10 years: 31%). DHHS, Department of Health and Human Services; ITA, internal thoracic artery; YO, year old.
