In addition, complicated diabetes was negatively associated with infection for the HDL group (16% vs. 15%, p < 0.001), while uncomplicated diabetes was positively associated with infection in both groups (26.1% vs. 26.5% for the HDL group, and 28% vs. 36% for the apoA1 group; both p < 0.001). The gene discussed is APOA1; the disease is infection.
