Change in physicians' perceived certainty of their patients' risk factor status during the 1
st year of the study. The generalized estimating equations approach was used to model differences in physician perceived awareness of risk factors pre and post 1st educational intervention. Values are expressed as adjusted and unadjusted odds ratios (OR) and corresponding 95% confidence intervals (CI) are reported. Generalized estimating equations method was used to take into account the clustered nature of the data (patients within physicians). All risk factors in figure 2 were included in the adjusted analysis. Overall Certainty = all the risk factors in figure 2 combined. UP = upper. The fit of the models ranged from 0.714 to < 0.001.
