Table 2 Continuous Variable Cut-points

From: A standard procedure for creating a frailty index

Variable Deficit for Men Deficit for Women Source of cut point
Peak Flow (liters/min) ≤ 340 ≤ 310 Plotted verses frailty index
Body Mass Index (BMI) <18.5, ≥ 30 as a deficit.
25-<30 as a 'half deficit'
<18.5, ≥ 30 as a deficit.
25-<30 as a 'half deficit'
