In this case this evidence is taken from the "National Center for Biotechnology Information" (an information center that is part of the National Library of Medicine) and shows the percentage of cases in which antibiotics were not prescribed correctly for two reasons the first one is that the antibiotic was not the correct one and the second one is when the antibiotic is the correct but the dosage (amount of time) is not.
