Table 3 Risk Factors that Affected the Overall Survival Rate Determined by the Cox Proportional Hazards model

From: Increased expression of integrin-linked kinase is associated with shorter survival in non-small cell lung cancer

Variable Relative risk 95%CI p-value
Tumor grade (mod., poor/wel) 1.238 0.858–1.786 0.2543
T status (T2, T3/T1) 1.845 1.208–2.818 0.0046
N status (N1, N2/N0) 3.897 2.241–6.775 <0.0001
Vascular invasion (positive/negative) 2,981 1.733–5.127 <0.0001
ILK (strong/weak or no) 1.844 1.093–3.112 0.0218
