Posted:  2006Oct16 
In the 2002 Time Series Study, four randomization assignment variables for alternate wording erroneously included all cases. The variables affected include V024412, V024413, V024415, and V024416. The following code (for SAS) will make the necessary corrections: if V024410 eq 2 then V024412 = .; if V024410 eq 2 then V024413 = .; if V024410 eq 2 then V024415 = .; if V024410 eq 2 then V024416 = .; run;
