Lymphocyte and lymphocyte subset counts (mean ± SE) among trichloroethylene (TCE) exposed workers and unexposed controls. Results previously reported in (Lan et al., 2010). Lymphocytes and lymphocyte subset counts in relation to TCE exposure level. P_trend using category of TCE levels (controls, <12 and ≥12 ppm) as a continuous variable (*P_trend < 0.05). The median TCE concentration of all exposed subjects was 12 ppm. Differences in cell counts were tested by linear regression analysis of ln-transformed end point, adjusting for relevant covariates [lymphocytes: adjusted for age and sex; CD4⁺, CD8⁺, and NK T cells: adjusted for age and sex, three subjects (two controls and one exposed) were deleted due to inconsistent cell counts using complete blood count data versus flow cytometry to calculate % lymphocytes; B cell: adjusted for age, sex, and smoking status].
