  1. ^ Unadjusted and adjusted effects were back-transformed from parameter estimates obtained using a logit link transformation. The z test was used for significance testing of model coefficients
  2. + Adjusted estimates describe the adjusted curve drawn in Fig. 4
  3. *Adjusted predicted percentage of nonusers citing financial barriers were obtained with all other coverages fixed their mean values
