Abstract:
In most cases, when papers reported that no significant difference was found in randomized clinical trials this is a result of the sample size being too small. For this reason it is important to design the sample size before any trials or tests are carried out. To this end, we would like to introduce some reference material concerning determination of sample sizes for clinical trials and basic research, as well as some software for determining sample size designed for personal computers.
