Fig. 3: Multivariable adjusted restricted cubic spline model for body mass index and frailty level and disability risk among older adults.

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

Fig. 3

Body mass index and disability risk among (A) total participants, individuals with (C) frailty and (D) non-frailty. B frailty level and disability risk in total participants. The histogram shows the distribution of body mass index or Kihon checklist score. Solid lines represent hazard ratios, and dashed lines represent 95% confidence intervals (CIs). The hazard ratio was calculated based on a body mass index of 23.0 kg/m2 and Kihon checklist score of 0 point as reference. 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.
