Among those complications, some were more likely to be associated with anti-TNFα treatment: macular edema [OR = 11.25 (2.85–43.81), p = 0.0005], cataract [OR = 11.87 (2.37–59.49), p = 0.0026], and band keratopathy [OR = 12.89 (2.05–80.90 p = 0.0064]. The gene discussed is TNF; the disease is macular retinal edema.
