You seem to have coded your variables as 1,2 instead of 0,1:
*----------- begin example ------------- webuse mccxmpl, clear // code unexposed /exposed as 1, 2 // instead of 0, 1 gen case_wrong = case + 1 gen control_wrong = control + 1
// add some labels
label define lab 1 "no" 2 "yes"
label val case_wrong control_wrong lab
// see the crosstab
tab case_wrong control_wrong [fw=pop]
// -mcc- looks all wrong
mcc case_wrong control_wrong [fw=pop]
// if you use the 0,1 coding
// everything looks fine again
mcc case control [fw=pop]
*------------ end example -------------- (For more on examples I sent to the Statalist see:

Hope this helps,
Maarten
