Figure 3.

Overlap of frailty, comorbidity, and cognitive impairment in adults initiating hemodialysis. The overlap of frailty, comorbidity, and cognitive function is displayed through a Venn diagram. The percentages represent the proportion of the total population with only cognitive impairment, comorbidity, and frailty as well as the overlap of these three factors. Frailty is defined as ≥3 components as defined by Fried. Comorbidity is defined as ≥4 conditions as specified in the Materials and Methods. Cognitive impairment was defined as a Modified Mini-Mental State (3MS) score <80. The total represents 323 study participants on hemodialysis. The size of each subgroup is indicated in parentheses.
