This systematic review and meta-analysis separates subjective xerostomia from objectively measured salivary-gland hypofunction in representative populations aged 50 or older. Diagnostic criteria, age structure, medication and comorbidity still drive substantial heterogeneity.
Key findings
- This systematic review and meta-analysis separates subjective xerostomia from objectively measured salivary-gland hypofunction in representative populations aged 50 or older. Diagnostic criteria, age structure, medication and comorbidity still drive substantial heterogeneity.
Why this matters globally
This work adds internationally comparable evidence in Health sciences and defines questions for replication in other populations or systems. Its global value lies in the evidence and transferable reasoning, not in a single impact score.
