Kaplan—Meier survival curves.

Abstract

<p>Probabilities of (A) overall survival with log-rank test: χ² = 60.89; <i>P</i> ≤ 0.001 in the four groups and χ² = 2.02; <i>P</i> = 0.364 in the three PAOD groups. (B) Cardiovascular survival with log-rank test: χ² = 45.24; <i>P</i> ≤ 0.001 in the four groups and χ² = 0.69; <i>P</i> = 0.708 in the three PAOD groups.</p
