^aModel 4: Random intercept linear-mixed model with main effect, time, and main effect × time interaction term.

^bModel 5: Random intercept linear-mixed model additionally controlling for age at baseline blood draw, current and past smoking status, and log-transformed BMI (kg/m²).

^cModel 6: Random intercept linear-mixed model additionally controlling for age at baseline blood draw, current and past smoking status, and log-transformed BMI (kg/m²), white blood cell count, neutrophil%, lymphocyte%, monocyte%, and eosinophil%.

^dP-values < 0.05 were considered statistically significant.
