Associations of aging trajectories for an index of frailty score with mortality and medical and long-term care costs among older Japanese undergoing health checkups.

Medical and care needs greatly increased for the second and third trajectory groups when their frailty level was progressed in later life. Geriatr Gerontol Int 2020; 20: 1072-1078..
