Hi Bev,

Assuming you are measuring the same outcomes, you could definitely use Outcome Classification Codes set up for those outcomes at different times.

A lot will depend on the kind of analysis you wish to undertake later, but hopefully using outcome classification codes will do the job...

Do let us know if you need further information or want to discuss the particulars of your review in further detail.

Kind regards,

Hi Zak,

To further clarify. I am looking at the differece between an outcome at baseline and at the end of an intervention. Often this mean difference is not stated but I can calculate from information in the papers being reviewed. Can EPPI calculate the mean difference (assume T-test) or so I have to calcualate independently and then enter the MD manually into the outcome data?

Thanks

Bev
