  1. Data are n (%), MD (95% CI) or OR (95% CI), unless otherwise specified. Percentages may not add up to 100%, as they are rounded to the nearest percent
  2. CI, confidence interval; HbA1c, glycated haemoglobin; MD, mean difference; N/A, not applicable; OR, odds ratio; SD, standard deviation; TCC, total contact casting
  3. SI conversion factor: To convert HbA1c to proportion of total haemoglobin, multiply by 0.01
  4. *Significant difference between ‘< 4 months’ and ‘> 4 months’ median TCC duration groups, p < 0.05
  5. aPast or current smoker
  6. bMaximum missing data were for glycated haemoglobin (HbA1c) involving 1 participant overall (3.7%)
