^a Robust SE clustered on the individual.

^b Weight (kg)/height (m)².

^c All models adjusted for age, Charlson comorbidity index, medication use, Medicaid enrollment, month, year, measurement method, and neighborhood variables.

^d With the non-ITT approach, participants’ residences were modeled using their actual address.
