proc mianalyze for adjust p value

[superbibi]

Hi, 

I have a sample dataset for multiple imputation and I will use proc mianalyze. 

I encounter two problems:

1. When visit 2 has no missing, the outcome of proc mianalyze does not show the p-values.

2. How can I get the adjusted p-values from proc mianalyze procedure. 

DATA FORMI (keep=person gender y1-y4)
formixed(keep=person gender visit y);
input person gender$ y1-y4;
output FORMI;
