Dr. Kodishala et al reply.

We thank Wang and colleagues 1 for their earnest interest in our recent paper, which evaluated the risk factors for dementia in an inception cohort of rheumatoid arthritis (RA). 2 In their correspondence, 1 the authors point out a possibility of confounding by several factors, including age, sex, education, calendar year of RA incidence, and race, and suggest adjusting for these confounders.
