According to the results reported on ClinicalTrials.gov, this trial looked at four different antibiotic nasal saline rinses used to treat sinus infections after surgery. The four groups were: mupirocin, tobramycin, levofloxacin, and vancomycin — each mixed into a saltwater nasal rinse. A total of 19 people started the trial across all four groups (12, 1, 5, and 1 respectively), and 17 completed it. The two who did not finish were both in the mupirocin group. The trial was measuring whether participants developed new antibiotic-resistant organisms (germs that become harder to treat), and also tracked changes in participants' self-reported sinus symptoms and physical examination scores. The reported data shows that, for the main outcome — new antibiotic resistance detected by nasal swab — zero participants in the mupirocin, tobramycin, and vancomycin groups developed new resistant organisms, while one participant in the levofloxacin group did. For the symptom survey (scored 0–110, where higher means worse symptoms), the reported changes were: mupirocin −18, tobramycin +14, levofloxacin −25.5, and vancomycin −11. A negative number means scores went down (i.e., reported symptoms decreased), while the tobramycin group showed an increase. For the physical examination score (scored 0–12, where higher means more signs of sinus disease), the reported changes were: mupirocin −5.3, tobramycin −3, levofloxacin −2.4, and vancomycin 0. It is worth noting that most groups were very small — particularly tobramycin and vancomycin, which each had only one participant — so these figures should be understood in that context.
