From: Immune biomarkers link air pollution exposure to blood pressure in adolescents
Immune markers and immune cell types associated with air pollution exposure. Heat map of immune markers and immune cells (VIP > 1.4) in PLS models explaining variability in recent exposure to air pollutants. Red are positive and blue are negative correlations. Analyses accounted for the variability in age, sex, BMI, asthma and smoking. PLS indicates partial least squares; VIP, variable importance in projection. CO, carbon monoxide; NO, nitrogen oxide; NO2, nitrogen dioxide; O3, ozone; PAH, polycyclic aromatic hydrocarbon; PM, particulate matter
