Emerging evidence suggests that inflammation and vascular dysfunction may play a role in its pathogenesis. C-reactive protein (CRP), a marker of systemic inflammation and atherosclerosis, has been widely studied as a prognostic indicator in various diseases. However, its potential association with NTG remains unclear. This meta-analysis aims to clarify the relationship between CRP levels in individuals with NTG compared to those without the condition.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We systematically searched PubMed, Embase, and Scopus for observational studies published up to 31 October 2023 investigating CRP levels in NTG patients and controls.
