I am doing research on colorectal cancer for my master's degree in medicine. I have a total of 177 patients, out of which 5 have residual malignant disease after resection (primary endpoint). Due to the small number of events I want to perform a binary logistic regression analysis. I have never done this before, but have given it my best try. I know that I can find whether or not the variable is a predictive/a risk factor in the table called ''Variables in the equation'' under ''Sig.''. I consider a p value <0.05 significant. I have a problem interpreting my results. One of the factors I am looking at has a p value <0.05 so is significant, but there are also two factors with p values of 0.998 and 0.997. Those two factors look at morphology of the colorectal polyp and the ASA-score, which are both categorical. All patients with an event fall into the same categories for morphology and ASA-score, which makes me wonder whether I should interpret those two p values as significant too. Can anybody please help me explain whether those p values are significant or not?

Thank you!
