Evidence Based Practice: Level "A" Type of Evidence Randomized control trials (rct) are considered to be the preferred study design. Participants are selected and assigned randomly and undergo very controlled conditions. Evidence based practice: Level "B" Type of evidence Well designed control trials without randomization are less strong in validity due to the lack of control of variables at the initiation of a trial. Some concerns or problems with this type of trial include inten...
