Most of the other comorbidities, including hypertension (57% vs. 50%), cerebrovascular disease (12% vs. 7%), congestive heart failure (12% vs. 8%), heart failure (15% vs. 11%), hemiplegia (3% vs. 2%), ESRD (2% vs. 1%) and transplant (1% vs. 0.6%), were negatively correlated with infection for the HDL group (p < 0.001), but not for the apoA1 group (p > 0.05). The gene discussed is APOA1; the disease is infection.
