In a trial treating a common infection, patients given a 5-day antibiotic course relapsed no more often than those given the standard 10-day course. The shorter-course patients also carried fewer drug-resistant bacteria afterward. Both groups received the same drug at the same daily dose.
these statements most strongly support which of the following?
- For this infection, halving the course length was not associated with more relapses despite reducing later resistant-bacteria levels.
- For this particular common infection, the 5-day antibiotic course is a more effective cure than the standard 10-day course is.
- Shorter antibiotic courses are clearly the preferable treatment option for treating every single type of infection there could be.
- The standard 10-day antibiotic course is the single factor responsible for causing most cases of antibiotic resistance seen worldwide.
- Patients who had been assigned to the longer 10-day antibiotic course must have been taking a noticeably higher daily dose of the very same drug.
