Majority of the subjects (92.7%) in the low risk category remained in the same risk category at 1 year follow up. Among subjects in the moderate risk category nearly two third (61.3%) remained in the same category, however approximately one third (35%) moved to the low risk category. In the high risk group 36.4% subjects shifted risk down two categories, from high to low and 45.5% subjects shifted one category from high to moderate. There were significantly higher proportion of participants in the low risk category and lower proportion in high risk category at 1 year follow up in comparison to baseline assessment.(Mc Nemar <.01)
