Table 2
Prediction, reliability and influence level measures of diagnostic probability in patients with SPs after
considering a clinical high index of suspicion related to the initial evidence of an endonasal polypoid
mass. This was correlated with each of the imaging findings observed in these patients (CT scan and
contrast-enhanced MRI). Coefficients of diagnostic probability estimates in all correlative comparisons
show coefficients that reveal a high effect of diagnostic efficiency in the patients with SPs in our
investigation
