CD4 and periodontitis: Lastly, in the morphological parameters, having periodontitis led to an increase in FSC-A on monocyte (Beta = 0.13 [0.11, 0.14], P = 0.03), FSC-A on B cell (Beta = 0.15 [0.13, 0.16], P = 0.03), FSC-A on HLA DR + T cell (Beta = 0.14 [0.12, 0.15], P = 0.02), SSC-A on myeloid Dendritic Cell (Beta = 0.19 [0.17, 0.22], P = 0.00), SSC-A on plasmacytoid Dendritic Cell (Beta = 0.12 [0.11, 0.13], P = 0.04), SSC-A on B cell (Beta = 0.15 [0.13, 0.17], P = 0.04), and SSC-A on HLA DR + CD4 + T cell (Beta = 0.15 [0.13, 0.17], P = 0.02).
