Figure 2.

Distribution of baseline cognitive function scores, by frailty status in adults initiating hemodialysis. The distribution of the cognitive function scores at baseline is presented as a boxplot. The median (center bar), 25th percentile (bottom of the box), and 75th percentile (top of the box) are plotted by frailty status. Outliers (data points that fall outside the lower quartile −1.5 × IQR, upper quartile +1.5 × IQR) are noted as dots. (A) Modified Mini-Mental State (3MS) test. (B) Trail Making Test A (TMTA). (C) Trail Making Test B (TMTB). IQR, interquartile range.
