aBinary variables: no lymph node involvement versus otherwise; nonmetastasis versus otherwise; nonsmoker and smoker for ≤15 years versus smoker for >15 years. bConstant or linear covariance makes N stage = pathological stage. HR: hazard ratio; CI: confidential interval; vs.: versus. Statistically significant results (in bold).
