Overview

Meta-analysis reveals sugar-free chewing gum reduces thirst and xerostomia in maintenance hemodialysis patients, indicating a potential low-cost intervention.

  • The analysis included seven studies with 395 participants, showing significant reductions in both thirst and xerostomia scores.
  • The meta-analysis followed PRISMA guidelines, utilizing a systematic approach to literature screening and data extraction.
  • Despite positive findings, the overall evidence quality was low, calling for more extensive and rigorous future studies.
