En un estudio titulado: "Calcium Supplementation and the Risks of Atherosclerotic Vascular Disease in Older Women: Results of a 5-Year RCT and a 4.5-Year Follow-up":

"Fourteen hundred and sixty women were recruited from the electoral role for the Calcium Intake Fracture Outcome Study (CAIFOS), a 5-year population-based study of **ambulatory Western Australian women** aged over 70 years designed to investigate the efficacy of calcium supplementation in preventing fracture. A recruitment letter was sent to 24,800 potentially eligible women using the electoral roll. Because voting is compulsory for adult Australians, nearly 100% of women of this age are registered. Potential participants were excluded if they had an illness likely to limit involvement in the study for 5 years or they were taking bone-active agents such as bisphosphonates or estrogen. "

En este caso, ¿se trata de personas que reciben un tratamiento ambulatorio o se refiere a mujeres que son capaces de deambular?
