Average normalized accuracy as a function of the available information for diagnosis. All tested combinations provided concave-shaped curves, indicating that there is an optimum quantity of available information to accurately perform pattern differentiation. Also, inspection (Ip) or its combination with auscultation-olfaction (Ip+AO) provided lower average normalized accuracies than addition of inquiry (Ip+AO+Iq) and palpation (Ip+AO+Iq +P; Four Examinations) to the examination, as indicated by the relative position of the concavity (maximum value).
