The questions in 1793 nitrofurantoin and 862 fosfomycin concern acute uncomplicated cystitis in women. UTI in men has traditionally been classified as a complicated infection; these results must not be combined with uncomplicated cystitis in women. The original recurrence fractions, rates, −3.0 difference and CI are each recorded unchanged. Parenthetical rates or differences are not recalculated from fractions, and the original table or observation window is not corrected.

The same report or population, sibling questions, groups, time points, denominators and article references are not added as new independent trials or participants. Report or material slots are not unique clinical totals; independent totals are null. S02 is an existing cross-citation reference to article 1793 on nitrofurantoin and clinical cure of acute uncomplicated cystitis in women, B70. The linked article or trial has not been read in this preparation; its population, exposure and endpoint differ from 28-day recurrence in afebrile men. The same report or population, sibling questions, groups, time points, denominators and article references are not added as new independent trials or participants. Report or material slots are not unique clinical totals; independent totals are null. S03 is an existing cross-citation reference to article 862 on single-dose fosfomycin for uncomplicated cystitis in nonpregnant women, B62. The linked article or trial has not been read in this preparation; its population, exposure and endpoint differ from 28-day recurrence in afebrile men. The same report or population, sibling questions, groups, time points, denominators and article references are not added as new independent trials or participants. Report or material slots are not unique clinical totals; independent totals are null. | Material | Public availability | Access status | Actually read | Notes | |---|---|---|---|---| | Stored summary | Stored file | Stored summary | Summary read | Only the stored JSON summary and bibliography were used for production.

They do not constitute official assessment-tool certification or a new efficacy score. - M03 [Cochrane Handbook 6.5 (2024), chapter updated 2023-08](https://www.cochrane.org/authors/handbooks-and-manuals/handbook/current/chapter-03) · §3.1, §3.2.1–3.2.3, MECIR C5/C7/C13 · Clearly record the question, eligibility conditions and reasons for changes, and distinguish variations in interventions. · Preserved method HTML copies; no current method-content re-review or official tool execution - M04 [Cochrane Handbook 6.5.1 (2025), chapter updated 2025-03](https://www.cochrane.org/authors/handbooks-and-manuals/handbook/current/chapter-04) · §4.5, §4.6.1–4.6.3, MECIR C42 · Distinguish studies from reports and link them; do not omit a study solely because results are unreported. · Preserved method HTML copies; no current method-content re-review or official tool execution - M08 [Cochrane Handbook 6.5 (2024), chapter updated 2019-10](https://www.cochrane.org/authors/handbooks-and-manuals/handbook/current/chapter-08) · §8.1–8.2.3, Table 8.2.a · Define the outcome and effect of interest, then examine randomization, deviations, missing data, measurement and selective reporting. · Preserved method HTML copies; no current method-content re-review or official tool execution - M15 [Cochrane Handbook 6.5 (2024), chapter updated 2023-08](https://www.cochrane.org/authors/handbooks-and-manuals/handbook/current/chapter-15) · §15.2.4, §15.3.1–15.3.3 · Distinguish effect estimates, intervals, importance and applicability.

This production does not declare that review complete. - Partly verified: Some information in the stored summary is linked into the table. External comparison/content review is not complete. - Unverified: The article leaves this unverified, or required material is absent from the current stored summary. This is distinct from zero, absence or safety. - Review incomplete: User review pending. - Not reported: Not reported within the stored material actually read; not extended to the entire primary paper. - Inaccessible: Means an actual access failure. Access not attempted here is not assigned this state. - Not applicable: Not used as a substitute for an evidence gap. - Conflicting data: Requires an observed disagreement under the same comparison criteria; not automatically judged in this production. - Insufficient evidence for the conditions: Marks a gap in additional material required by the selected conditions; not a new efficacy grade. ## Change history 2026-10-10 · Public page/materials 1.0.
