CRITICAL ILLNESS, CRITICALLY ILL
Data was collected from the time of study enrollment until 90 days or hospital discharge (whichever occurred first). At enrollment, families completed a questionnaire to help understand their interest in research on VDD in critical illness and inform primary outcome selection for a subsequent Phase III trial. More specifically, families were asked to indicate, other than mortality, the three most important outcomes for a research study evaluating rapid restoration of vitamin D status in critically ill children, and then to indicate all of the outcomes they would consider important.
