Relationship between the FI-CSHA and the FI-LAB. FI-LAB values were plotted as a function of the FI-CSHA scores. The FI-CSHA scores were pooled and the means (±SEM) are shown in increments of 0.05. The FI-LAB increased as FI-CSHA scores increased (P <0.001). The data were fit with a linear regression as described in the methods and were a good fit to a straight line (r2 = 0.81). FI-CSHA, standard frailty index; FI-LAB, laboratory frailty index; SEM, standard error of the mean.
