The prognostic value of PNI on overall survival curves in patients with EGFR exon 19 deletion or L858R.

<p>(<b>A)</b> Comparison of OS on patients with high PNI vs low PNI. (<b>B)</b> Comparison of high PNI vs low PNI in patients with EGFR exon 19 deletion. (<b>C)</b> Comparison of high PNI vs low PNI in patients with EGFR L858R.</p

The optimal cut-off point plots generated by the biostatistical tool, <i>Cut-off Finder</i>.

<p>The vertical line designates the optimal cut-off point with the most significant <i>(log-rank test)</i> split.</p

Forest plot for subgroup analysis of overall survival.

<p>Survival is for high PNI vs low PNI. Data are derived from Cox’s analysis without covariates.</p
