*The p values are based on cross-tabulation with χ2-test.
†At ERA group six drop-outs, at CRA group three drop-outs for personal reasons.
‡ERA and CRA are compared at baseline and follow-up, p value by non-parametric McNemar's test, related samples.
The figures are frequencies (N=number of patients) with percentages.
a bEach subscript letter denotes a subset of study group categories whose column proportions do not differ significantly from each other at the 0.05 level.
