According to Allen and Sirota,^[1] ^[2] Non-bacterial thrombotic endocarditis may be classified according to morphology into 5 subtypes:

Allen and Sirota macroscopic classification of NBTE
Type of NBTE	Features
Type 1	Small < 3 mm Univerrucal Firmly attached to the valve
Type 2	Large > 3 mm Univerrucal Adherent to the valve
Type 3	Small 1 - 3 mm Multiverrucal Friable
Type 4	Large > 3 mm Multiverrucal Friable
Type 5	"Healed-type" Similar in consistency to the attached valve

 ==Overview==
-There is no established system for the classification of [disease name].
-OR
-[Disease name] may be classified according to [classification method] into [number] subtypes/groups: [group1], [group2], [group3], and [group4].
-OR
-[Disease name] may be classified into [large number > 6] subtypes based on [classification method 1], [classification method 2], and [classification method 3].
-[Disease name] may be classified into several subtypes based on [classification method 1], [classification method 2], and [classification method 3].
-OR
-Based on the duration of symptoms, [disease name] may be classified as either acute or chronic.
-OR
-If the staging system involves specific and characteristic findings and features:
-According to the [staging system + reference], there are [number] stages of [malignancy name] based on the [finding1], [finding2], and [finding3]. Each stage is assigned a [letter/number1] and a [letter/number2] that designate the [feature1] and [feature2].
-OR
-The staging of [malignancy name] is based on the [staging system].
-OR
-There is no established system for the staging of [malignancy name].
