Solitary Pulmonary Nodule Malignancy Risk (Mayo Clinic model)

Input:

Age
Smoker	Current or former (1)
	Never smoker (0)
Cancer	Extrathoracic cancer more than 5 years prior (1)
	None (0)
Nodule Diameter
Spiculation	Yes (1)
	No (0)
Upper Lobe	Yes (1)
	No (0)

Results:

X
Malig Probability

Decimal Precision:

Formula Notes References

X = (0.0391 * Age) + (0.7917 * Smoker) + (1.3388 * Cancer) + (0.1274 * NoduleDiameter) + (1.0407 * Spiculation) + (0.7838 * UpperLobe) - 6.8272

MaligProbability = 100 * e^(X) / ( 1 + e^(X))
