Data are n (%) or mean (SD), unless otherwise specified. Percentages may not add up to 100%, as they are rounded to the nearest percent
ABPI, ankle-brachial pressure index; SD, standard deviation; TBPI, toe-brachial pressure index; TCC, total contact casting
*Significant difference between ‘< 4 months’ and ‘> 4 months’ median TCC duration groups, p < 0.05
aPeripheral neuropathy was defined as a monofilament score < 3/3 either foot
bPeripheral arterial disease was defined as absence of ≥2 pedal pulses, TBPI ≤0.6, and/or ABPI ≤0.9 either foot
†Maximum missing data were for right TBPI involving 25 participants overall (92.6%). Missing data were for pedal pulses (n = 1), ABPI (n = 15), left TBPI (n = 24), right systolic toe pressure (n = 23), and left systolic toe pressure (n = 20)
cAs a result of missing data pertaining to toe systolic pressures, ankle systolic pressures and/or TBPI scores, data reported are the raw data for one participant only. Therefore, mean (SD) were unable to be calculated and reported
