	Classification based on surgical findings (No. of secondary extensions detected)				Overall accuracy
	Absent (37)	Intersphincteric (7)	Ischiorectal (19)	Supralevator (3)	Overall accuracy
Physical examination
Absent	24¹	1	3
Intersphincteric	5	4¹	3	2
Ischiorectal	8	2	12¹		62.1% (41/66)^a
Supralevator	0	0	1	1¹
3D-EAUS
Absent	32¹	0	2	1
Intersphincteric	2	5¹	1	2
Ischiorectal	3	2	16¹	0	81.8% (54/66)^b
Supralevator	0	0	0	1¹
H₂O₂ 3D-EAUS
