Expression Levels of Some Antioxidant and Epidermal Growth Factor Receptor Genes in Patients with Early-Stage Non-Small Cell Lung Cancer

Figure 2

Kaplan-Meier plot of survival times in NSCLC patients classified by expression ratio levels of HER-2 transcript in cancerous versus unaffected tissues (up to or higher than one). The dashed line represents subjects over-expressing HER-2 mRNA in the cancerous versus unaffected tissues, whereas the continuous line indicates subjects with lower expression levels of HER-2 mRNA in cancerous versus unaffected tissue samples. Crosses indicate censored subjects, represented by patients still alive at 1st April 2008.
