 T cell subpopulations and activated T cells in peripheral blood in controls and in patients with active and inactive dermatomyositis

Patients with aDM (n = 29)Patients with iDM (n = 20)Controls (n = 32)p Values
aDM v controliDM v controlaDM v iDM
Values are mean (SD). Significant p values in bold.
The samples were measured by flow cytometry and lymphocytes were identified on the basis of their scatter properties.
aDM, active dermatomyositis; iDM, inactive dermatomyositis.
