Figure 3: Diagnostic accuracy and total practice time are plotted against the total number of modules practiced. The solid line curve is the Gompertz curve that estimates diagnostic accuracy. The dashed curve is the Michaelis-Menten curve that estimates total practice time. Grey shaded regions represent 95% CI. The horizontal and vertical dotted line shows an exemplar 80% diagnostic accuracy mapping to the estimated number of modules and total practice time required to obtain this competency level. See also tab. 3 for calculated values.
