Therefore, significant differences were detected among younger and older individuals within the infection-primed group for IL-6 (12.01 pg/mL [95% CI 11.42-12.60] for< 60 years old vs. 10.65 pg/mL [95% CI 9.53-11.78] for > 60 years old, P = 0.0387) and adiponectin (6.32 μg/mL [95% CI 5.86-6.77] for< 60 years old vs. 3.32 μg/mL [95% CI 2.07-4.56] for > 60 years old) concentrations. The gene discussed is IL6; the disease is infection.
