The diagnostic power of salivary electrolytes for Sjögren's disease: a systematic literature review and meta-analysis.

Objectives: To perform a systematic review and meta-analysis to determine the power of salivary electrolytes for the diagnosis of Sjögren's disease (SjD).

Methods: A literature search was conducted (last search March 2023) using PubMed and Web of Science and completed with a manual search. Articles were screened for reports of human salivary ion concentrations, comparing SjD patients with healthy controls and/or sicca patients.
