All length measurements were done blind to the status of the AD or controls using double blind labeling system of the glass slides.
Study drug infusions (clevidipine or placebo) were identical in appearance; to maintain the single blind, labels were covered while infusions were administered.
It's worth noting that the "need-blind" label can be as much about marketing as it is about giving all applicants a fair shot.
Wesleyan University last year took the other route, announcing it would give up the "need-blind" label and start to consider students' financial need once its aid dollars were given out.
Unless schools pony up the aid dollars to meet students' financial needs, touting the need-blind label isn't particularly meaningful for students, who may simply get the offer of admission along with an offer to take on unsustainable debt.
Most registries offer specific coded fields for blinding (open label, single blind or double blind) or a description of masked roles (subject, caregiver, investigator, outcomes assessor).
Examples are the design of the randomized assignment (conventional, crossover, parallel group, 2 × 2 factorial) or the method of blinding (single or double blinded, open label).
The study included four distinct phases: screening, double-blind, open-label, and safety follow-up.
Shipping and packing: All trial products will be delivered, packed blinded and labelled by Novo Nordisk A/S.
This is a randomized double-blind open-label study including nearly 15,000 patients in which co-administration of either sitagliptin or placebo was implemented on top of their previous antidiabetic treatment.
Rates were computed for the double-blind period, as well as the cumulative (double blind and open label) study period.
