Figure 3From: Highly frequent promoter methylation and PIK3CA amplification in non-small cell lung cancer (NSCLC) Relationship of promoter methylation (Odds Ratios) with tumor characteristics of NSCLC. Multiple univariate logistic-regressions were performed with the use of methylation data for the 6 genes that were defined as 'positive' or 'negative' through receiver operating characteristic (ROC) curves. Details are as described in Methods. *, P < 0.05.Back to article page
