  1. * Contained missing numbers (housing type, 2; and number of hours spent sitting or reclining daily, 1)
  2. + The aPR of the variables that were not significant at the 5% level was obtained by incorporating that particular variable in the final multivariable model
  3. # These variables were significant at the 5% level and were included in the final multivariable model using the backward stepwise approach
  4. ^ The p value for trend was 0.02
