Fig. 3

Cumulative transition probabilities of frailty for participants exposed to the social isolation. Owing to the high number of deaths in the second 10 years of follow-up, this graph shows the cumulative transfer probabilities of frailty states exposed to social isolation (purple) or not (yellow) during the first 10 years, and the differences in cumulative transfer probabilities in females (continuous) and males (dotted). A (for all participants) and 3E (stratified by sex) show the transitions from non-frailty to prefrailty, whereas B (for all participants) and 3Â F (stratified by sex) show the transitions from prefrailty to frailty; C (for all participants) and 3G (stratified by sex) show the transitions from prefrailty to death; and D (for all participants) and 3Â H (stratified by sex) show the transitions from frailty to death. These models were adjusted for age, sex, education, household income, residence, childhood socioeconomic status, intake of vegetables and fruits, smoking, drinking, and regular physical exercise
