Overall survival of patients with T4 N0/1 M0 non-small cell lung cancer treated with definitive concurrent combination chemotherapy and radiotherapy (RCTx 1). For comparison, survival of NSCLC patients of the same TNM stage who received neoadjuvant radiochemotherapy and surgery were included (trimodal 2). The 95% confidence intervals for an inference at a single fixed time are shown as background areas of the same colour as the respective survivor functions. There were no significant differences between survival curves (p = 0.184, Log rank test)
