[EXTERNAL]RE: ASA Connect : Software for stratified randomization lists

    Dear Dr. Benn:

     

       Thanks so much for suggesting RRApp.   I have used it once already, and am preparing to use it to generate a large stratified permuted block randomization scheme, with just 2 treatment arms, but for 8 strata.

     

      When the program generates one of those, can you please answer these questions for me:

     

    1)      What is the size of the random permuted block (RPB) ?

     

    2)      Are the RPBs of the same size (i.e., length) for the entire randomization list for a given stratum ?

     

    3)      Or, can the program use RPBs of varying sizes (i.e., lengths) within a given randomization list ?

     

    4)      How can the user have control over those characteristics of the randomization list(s) ?

     

      I look forward to your reply.   Thanks again for informing me of RRapp.   Very useful.

     

                    ...  Lance Heilbrun.

    Perhaps you might want to consider using our free Robust Randomization App (RRApp): clinicalresearch-apps.com/RRApp.html .

     

    Briefly our app generates simple, stratified, block, stratified block, permuted block, and stratified permuted block randomization schemes.

     

    The generated randomization schemes can also be directly imported into REDCap if you'd like.

    Also, here is the citation if you would like to read more about our app:
