Feline malignant lymphoma: log-linear multiway frequency analysis of a population involving the factors of sex and age of animal and tumor cell type and location.

A method appropriate for the analysis of multiway frequency tables is described. This multivariate approach was used to evaluate the relationship between age, sex, cell type, and tumor location based on information available from 1,733 cases of feline malignant lymphoma. The analysis identified 6 bivariate relationships to be statistically significant, P less than 0.001; there were no significant higher order interactions observed. Emphasis was placed on 3 interactions: age to tumor location, age to sex, and tumor location to cell types.
