Table 1 Baseline characteristics of the physical examination group, the total study population and the completely physically capable group in 1994. Analysis of variance between the total population sample and the physical examination group are reported as the p-value

From: Cardiovascular and musculoskeletal health disorders associate with greater decreases in physical capability in older women
