Interaction visualization in PROC LOGISTIC

[LucyB]

I am running a proc logistic and am looking specifically at a 3 way interaction. Here is some descriptives on my data:

Outcome: mortality (y/n)

Var 1: gender (M/F)

Var 2: dichotomous lab value (above/ below certain critical cutoff- y/n)

Var 3: second dichotomous lab value (above/ below certain critical cutoff- y/n)

I am looking to see who is more at risk for the mortality outcome and have included an interaction for these terms in the model. My interaction p-value is not significant, but I want to report directions. Since I have 3 dichotomous variables, what would be the best way to present this (preferably graphically) in regards to who is more likely to experience mortality?

You can probably use 

effectplot interaction;

as documented here

Thank you, so this plots the probabilities for 2 of my predictors but fixes the value for my 3rd. I want to compare across all 3 somehow..

Look at the article "Visualize an ANOVA with two-way interactions" and see if you can figure out how to extend it to your three binary variables. You will end up with 6  box plots.
