  1. SPPB Short Physical Performance Battery; Sex was coded as male = 1, female = 2; Education was coded no education, primary = 2, secondary = 3, college/university = 4; self-rated health was coded as excellent = 1, good = 2, fair = 3 and poor = 4. IMD = Index of multiple deprivation. 1 is least deprived and 4 is most deprived
  2. B Unstandardized regression coefficient; SE Standard error of the coefficient; CI Confidence interval; *P value < 0.05; **P value < 0.01
