Question

A study published in a 2003 volume of the journal Clinical Infectious Diseases was conducted between 1995-1997 across many hospitals. The study investigated a dangerous fungal blood infection called candidemia that had developed in regular patients at these hospitals. It was observed that about 1,600 adults and children who developed the infection over the two years were given one of two antifungal treatments, a combination of both antifungal treatments, or none of these. Investigators looked forward in time and made a comparison between the rates of mortality three months after treatment to see 1) whether adults or children had significantly higher mortality rates, and 2) whether any specific antifungal drug was better than the others. It was found that adults had a significantly higher mortality rate than children three months after treatment. It was also found that adults appeared to better respond to one of the antifungal treatments than any of the others

The correct choice is D) prospective study because in a prospective study the researcher watches for outcomes, such as the expansion of a disease, throughout the study period and relates this to other factors such as assumed risk. The study generally involves taking a cohort of subjects and watching them over a period of time.
