  • Exclusion criteria: Studies not involving cranberry products for UTI prevention, non-randomized controlled trials, and quasi-RCTs

Interventions

  • Experimental group: Cranberry products
  • Control group: Placebo, no specific treatment, or other interventions (antibiotics, probiotics)

Primary outcome

Significant difference? Yes, for women with recurrent UTIs, children, and people susceptible to UTIs following interventions. No significant difference for elderly, pregnant women, or adults with bladder dysfunction.

Secondary outcomes

Comparison of cranberry products to antibiotics, probiotics, different cranberry product forms (tablets, liquid), and different doses of PACs

Safety outcomes or Adverse Events

Gastrointestinal side effects: No significant difference between cranberry products and placebo or no specific treatment
