Abstrakt: In their paper discussing the importance of double-blinding in controlled trials, Furberg and Soliman stated that one of the established and fundamental principles for avoiding the problem of bias is to keep the study participants and the investigators blinded, or masked, to the identity of the assigned interventions. As a support to this argument they described the subgroup findings of Karlowski et al.s trial, which examined the effect of vitamin C supplementation on the commoncold[2,3]. Furberg and Soliman put a great weight on the importance of double-blinding, yet they are lax on other fundamental principles of controlled trial.
