Van Nood Et Al

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.
-Explain what the value 0.69 means, as if to someone who has never studied probability or statistics.

A) In the long run, about 69% of Clostridium difficile patients given a fecal transplant will be cured.
B) In the long run, about 69% of Clostridium difficile patients will be cured.
C) In the long run, about 69% of Clostridium difficile patients given the antibiotic vancomycin will be cured.
D) In the long run, about 69% of Clostridium difficile patients that were cured were given a fecal transplant.
