Indeed, the first call for a randomized controlled trial for such instruments was made in 1980.4 The University of Massachusetts Medical School study responded in 1987.3 The important point is that, just as soon as technical feasibility is available, diagnostic methods, like therapeutic methods, should have the most objective evaluation: in contemporary terms that means a randomized controlled trial.
