Elevated RBC ω-3 HUFA scores are associated with reduced mononuclear cell infiltration into lung alveolar fluid of cSiO₂-triggered NZBWF1 mice. BALF was assessed for (A) macrophages, (B) lymphocytes, and (C) neutrophils by differential cell counts, as determined by morphological assessment of 200 total cells on cytological slides. Counts between diet groups were normalized by log transformation and standardized by autoscaling. The normalized and standardized data was plotted against the ω-3 HUFA score for each animal. The data was analyzed by a simple linear regression and goodness of fit presented as R². Regression coefficients were considered statistically significant at p < 0.05. Shaded bands around regression lines represent 95% confidence intervals.
