^aBased on Poisson regression Model 2 of material and social deprivation and potential interaction with urban and rural residence.
^bAssuming that on a continuous scale, a 0.7 change in PCA score equates approximately to a change from one quintile level to the next.
^cOne-tailed test.
^dWhere 'urban' is defined as rural = 0; urban = 1 in Poisson regression model.
