Van Nood Et Al

Multiple Choice

Van Nood et al. (2013) studied patients with "Clostridium difficile" infections, which cause persistent diarrhea. One variable was treatment: some patients were given the antibiotic vancomycin, and some patients were given a fecal transplant. The other variable was whether the patient was cured (cured or not cured) . Van Nood randomly assigned an equal number of patients to each treatment. The researchers found that 18% of the patients in the antibiotic vancomycin treatment group were cured, whereas 69% of patients in the fecal transplant were cured.
