Welcome to the fecrt.com homepage
The study planning tool allows you to determine the minimum viable sample size for a FECRT study, given a set of user-supplied parameters such as expected efficacy and the size of the grey zone. This allows some additional flexibility around the standard guidelines provided by Kaplan et al. (2023).

The data analysis tool allows you to upload/enter one or more FECRT dataset to be analysed, and automatically generates the results for you based on the data uploaded. Basic results are shown on the screen, and a full report (including summary statistics) can be downloaded as a PDF or Word file.
