Controlling for multiple variables (C. pneumoniae IgG status, age, gender, BMI, CFH Y402H genotype, HTRA1rs11200638 genotype), logistic regression analysis indicated predictors for AMD status included increased BMI (p=0.015, OR 1.08, 95% CI: 1.01–1.14), increased age (p=0.015, OR 1.04, 95% CI: 1.01–1.08), female gender (p=0.011, OR 2.04, 95% CI: 1.18–3.51), and HTRA1rs11200638 homozygous (AA) status (p=1.45×10−4, OR 11.05, 95% CI 3.20–38.17). Here, CFH is linked to age-related macular degeneration.
