RegisterCV% and confidence interval [Software]
Hi,
I got a problem related to the CV% (from a parallel BE) and confidence interval. The CV% from winnonlin is ~14% but confidence interval is 74%-136%. Although the sample size for this trial is rather small (19 for analysis), the calculated CV% using confidence interval in PowerTOST is quite large (~39%). I'm not sure why the result is counterintuitive.
Anyone have ideas?
Sincerely,
Jietian
