Estimates of relative risk (RR) with 95% confidence intervals (95% CI) for independent factors in association with good lower body functioning (total short physical performance battery, SPPB scores ≥10, compared with poor functioning, or scores <10) from a multivariate, mutually-adjusted generalized Poisson model with log-link and robust standard errors. BMI = Body mass index; 3MSE = Modified Mini-Mental State Examination; CES-D = Centers for Epidemiological Studies depression scale; OTC = Over the counter
