Fig. 4: Forest plot and bar chart of the 50th percentile differences in age at disability and death for frailty and body mass index (BMI) status, calculated using the multivariable Laplace regression model.

From: Is a higher body mass index associated with longer duration of survival with disability in frail than in non-frail older adults?

A total participants (B) frailty stratified model. Results are presented as percentile differences (PDs) (95% confidence interval [CI]). To calculate the duration of survival with disability, we calculated the difference in the 50th PDs of disability and death events using the following equation: 50th PD of overall survival—50th PD of disability-free survival. If the results are greater than 0 (value is +), the duration of survival with disability is inferred to be longer. If the value is lower than 0, the participant is more likely to die before disability incidence. The adjustment factors are age, sex, population density, smoking status, alcohol consumption status, physical activity, sitting time, sleep time, family structure, educational attainment, economic status, denture use, medication use, number of chronic diseases, and/or frailty status.
