Combined hemorrhoidal disease classification.

Classification	Advantages	Disadvantages	Treatment relevance	Reproducibility	Practicality	Assessment value
PATE2006	Comprehensive; novel	Not associated with treatment modality		⋆	⋆	⋆⋆
Prolapsed hemorrhoid classification algorithm	Clear processes; easy to operate	Not associated with treatment modality		⋆	⋆	⋆⋆
PNR-bleed	Comprehensive; subdivision IV hemorrhoids; quantifying bleeding symptoms	Not associated with treatment modality; Lack of evidence-based medical evidence			⋆	⋆

If the hemorrhoidal disease classification fully satisfies the corresponding necessary factors ⋆; if the hemorrhoidal disease classification partially satisfies the corresponding necessary factors ✰; if the hemorrhoidal disease classification does not satisfy the corresponding necessary factors, no indication is given.
