That's likely some basic math so you could take the formula and calculate it manually but I would likely be checking PROC POWER to see if it could calculate that number. Are you assuming that the groups are equally sized as well? Ie 100 people? I believe the denominator may be important as well. If it heals 68 out of 1000 that's different than 68 out of 100 so you may need to be looking at rates instead.
