Prognostic factors for lymph node metastasis from upper gingival carcinomas.

There were no interactions between length parameters (e.g., bucco-lingual width, anterior–posterior length, and superior-inferior depth), although the anterior–posterior length variable approached significance (estimated coefficient: − 0.07, SE = 0.04, z = − 1.80, p = 0.07) indicating a trend towards an incidence for LN metastasis.
