This study aims to determine the association between chronic periodontitis and erythrocyte functional measures: total red blood cells (RBCs), hemoglobin (Hb) concentration, mean corpuscular volume (MCV), and mean corpuscular hemoglobin concentration (MCHC) by systematic review and meta-analysis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials and Methods:<\/jats:title>\n                    <jats:p>A systematic search of the electronic databases PUBMED, OVID, Embase, Web on Science, and Google Scholar was undertaken from inception to July 2022. English language studies that evaluated the erythrocyte functional measures in periodontitis and health were selected. Other review reports, letters\/opinion articles, studies without a definition of periodontitis, and the concomitant presence of systemic conditions (diabetes, kidney disease, cancer) were excluded.
