Abbreviations: AHR, adjusted hazard ratio; BMSCC, buccal mucosa squamous cell carcinoma; CI, confidence interval.
p values were estimated by multivariate Cox’s regression.
p values were adjusted for cell differentiation (moderate + poor vs. well), T classification(T3 + T4 vs T1 + T2), and N classification(N1 + N2 vs N0).
