Results where p<0.05 are highlighted in bold.
Accuracy levels were presented as number of people out of every 100 people who have a risk assessment whose risk will be overestimated [specificity]/underestimated [sensitivity].
Positive coefficients indicate a preference for the specified level compared to the reference; negative coefficients indicate a preference for the reference compared to the specified level.
