What is an open blinded endpoint study?
THE PROBE DESIGN The Prospective Randomized Open Blinded End-point (PROBE) study is a highly cost-effective alternative to the double-blind, prospective study design. This design utilizes a strict randomization procedure to allocate patients to different treatment regimens.
What is blinded endpoint?
The benefits associated with a strict randomization procedure are maintained and the incorporation of clearly defined, blinded endpoints helps to eliminate bias by allowing objective comparison of therapies and evaluation of the study results by an independent body.
Does open-label mean unblinded?
Open label trials are sometimes referred to as “non-masked” or “unblinded.” If the trial is a non-pharmacological study, such as a trial of devices, or psychological and physical treatments, it may be referred to simply as “open.”
