Fig. 2From: The assessment of serum-mediated phagocytosis of necrotic material by polymorphonuclear leukocytes to diagnose and predict the clinical features of systemic lupus erythematosus: an observational longitudinal studyDemographics and results of phagocytosis of necrotic cell material (PNC) assay in all the study participants. Age of the patients and percentage of double-positive polymorphonuclear cells (PI+CD66+ PMNs) are expressed as median values (range in brackets). The percentage of double-positive PNC results is significantly higher in patients affected by SLE compared with healthy controls and non-SLE patients in the multicenter rheumatic group.
