Risk factors for MRSA infection in dogs and cats retained in the final multivariable logistic regression model based on 176 records using animal as the unit of analysis (R 2 = 0.35). For variables with two categories the p-value is provided where as for variables with more than two categories an overall p-value based on a Wald-test is provided.
