  1. Data are n (%) or OR (95% CI), unless otherwise specified. Percentages may not add up to 100%, as they are rounded to the nearest percent
  2. CAM, controlled ankle motion; CC, calcaneocuboid; CI, confidence interval; CROW, Charcot restraint orthotic walker; IQR, interquartile range; N/A, not applicable; NC, naviculocuneiform; OR, odds ratio; SD, standard deviation; TCC, total contact casting; TN, talonavicular
  3. *Significant difference between ‘< 4 months’ and ‘> 4 months’ median TCC duration groups, p < 0.05
  4. aOne participant (3.7%) developed dermatitis. One participant (3.7%) experienced a plaster saw cut on removal of TCC
  5. bOne participant (3.7%) had a combination Charcot pattern involving the tarsometatarsal joints and the NC, TN and CC joints
