Figure 9. Cytokine and complement biomarker differences between individuals who are CF-NTM^NEG and CF-NTM^POS are pronounced in the RUL.

Lobe-specific cytokine and complement concentration data from all individuals in each cohort were analyzed via PCA to identify correlates of CF status and NTM infection history status. PCA scores for the first and second components of cytokine concentrations from the left lung lobes (A) LUL, (B) Ling, and (C) LLL, as well as the right lung lobes (D) RUL, (E) RML, and (F) RLL.
