Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Participants With Therapeutic Response (TR) (Combined Per Participant Clinical and Microbiological Response) at the Test-of-Cure (TOC) Visit - Micro-ITT NTF-S (IA Set) | Therapeutic response (success/failure) is a measure of the overall efficacy response. A therapeutic success referred to participants who had been deemed both a microbiological success(reduction of all qualifying bacterial uropathogens [greater than or equal to {>=}10^5 colony-forming units per milliliter {CFU/mL}] recovered at Baseline to less than (<)10^3 CFU/mL as observed on quantitative urine culture without the participant receiving other systemic antimicrobials before the TOC Visit) and a clinical success (resolution of signs and symptoms of acute cystitis present at Baseline [and no new signs and symptoms] without the participant receiving other systemic antimicrobials before the TOC Visit). Lack of clinical or microbiological success (including missing outcome assessments) was considered as therapeutic failure. | TOC visit (Days 9 to 16) | 
| Number of Participants With Therapeutic Response (TR) (Combined Per Participant Clinical and Microbiological Response) at the Test-of-Cure (TOC) Visit - Micro-ITT NTF-S Population | TR at TOC (success/failure) is a measure of the overall efficacy response.
