d Proven susceptibility of isolated uropathogens to the administered antibiotic, in case of positive urine culture.
e Resolution of the initially presented symptoms during follow-up; unknown symptom resolution is no symptom resolution. In case of missing data on symptom resolution at Day 10, symptom resolution at Day 5 was used.
