The IDEAL Framework describes the stages through which interventional therapy innovation normally passes, the characteristics of each stage and the study design types which we have recommended for each.

Further details are found in McCulloch et al, Lancet 2009; Sep 26; 374 (9695): 1105-12 and on the IDEAL website.

The RSTN is working closely with IDEAL on the NINJA study.

This page will be updated with further information in the near future.
