Correlation of genetic signatures with lifespan.

Abstract

<p><b>Panel A:</b> Some genetic signatures are associated with significantly different life-span. For example the most predictive signature (C1) comprises centenarians with significant longer survival compared to centenarians with signatures C2 or C26. (p-value 0.01 and 0.02) More examples are in <b><a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0029848#pone.0029848.s015" target="_blank">Figure S15</a></b>. <b>Panel B:</b> The two most predictive genetic signatures and the least predictive signature in the centenarians of the merged replications sets show consistent results. The comparison between survival of centenarians with the most predictive signature R1 and the least predictive signature R15 reaches statistical significance, (p-value = 0.003) while the comparison between survival distributions of centenarians with signatures R1 and R2 does not reach statistical significance (p-value 0.10).</p
