Distribution of monocyte subsets in early-onset OCD patients (N = 91) and healthy controls (HC, N = 34). a Percentage of total monocytes in OCD patients and healthy controls. b Percentage of all CD16+ monocytes, including CD14^highCD16^low and CD14^lowCD16^high monocytes, in OCD patients and healthy controls. c Percentage of classical (CD14^highCD16−), intermediate (CD14^highCD16^low), and non-classical (CD14^lowCD16^high) monocytes in OCD patients and healthy controls. Results are expressed as means ± SEM of the original data, prior to log transformation. Statistical analysis was performed using univariate general linear model adjusted for age and gender with natural-log-transformed data. **p < 0.01, ***p < 0.001, ****p < 0.0001
