Dear DLabes,

Thanks for your immediate and detailed reply...! I dont know how should I put it, (am feeling a bit stupid, actually), I put in this querry thinking that re: sample size calculations, basic rules qould be same for any kind of study.

We are actually calculating sample size for a clinical trial where the outcome is a continuous variable, and we are using 4 different treatments (3 drugs, 1 placebo), one cycle each for one individual. So I was trying to find out ways to calculate sample size, (but did not find anything really useful except the link above), then reached this forum and so asked my question in this post.

Thanks for your help,
Vidula
