Table 6 Multivariate logistic regression analyses with OxAFQ-C Emotional domain scores as the dependent variable a,b

From: The association of foot structure and footwear fit with disability in children and adolescents with Down syndrome

  OxAFQ-C Emotional domain scorec
Independent variables OR (95% CI)d Change in NagelkerkeR2 pvalue
Foot structure

  1. aAdjusted for sex, age and body mass index.
  2. bParent-reported Oxford Ankle Foot Questionnaire for Children (OxAFQ-C) domain scores were based on n = 49 due to missing data.
  3. cOxAFQ-C Emotional domain scores were dichotomised where the lowest quartile was classified as ‘disability’ and the upper three quartiles were classified as ‘no disability’.
  4. dOR: Odds ratio.
  5. eArch Index multiplied by hundred.
  6. fLogistic regression analyses performed for footwear fit were based on n = 48 due to missing data.
  7. gIll-fitting: representing the greatest disparity between the participant’s foot and footwear length and width dimensions; expressed as a percentage. The values that defined the lower median (ill-fitting) were as follows: length (shoe 14.3% shorter to 10.8% longer than foot), width (shoe 26.5% to 4.9% narrower than foot).
