Question

In their original report, Thys-Jacobs and colleagues† noted that the study was "double-blind." Explain what that means in the context of this example. The women taking the pills could not see the medical personnel with whom they interacted, and the medical personnel could not see the women. The women taking the pills did not know who had which type of pill (calcium or placebo) but the medical personnel with whom they interacted did know. The women taking the pills knew who had which type of pill (calcium or placebo) but the medical personnel with whom they interacted did not know. No one knew which women received which pills and it was determined who had been given which type of pill (calcium or placebo) by examining the data. Neither the women taking the pills or the medical personnel with whom they interacted knew who had which type of pill (calcium or placebo).
