Ref.	Year	Country	Study design	n	Procedure	Medication	Relative risk
Patai et al[66]	2014	Hungary	Prospective	29	Sphincterotomy	Thienopyridine (continued)	Incidence of delayed PPB 3.5%. Incidence of immediate/intraprocedural bleeding 3.5%
Ikarashi et al[68]	2017	Japan	Retrospective	1113	Sphincterotomy	Thienopyridine (ceased 5-7 d before)	Incidence of delayed PPB 3.0%. (study categorised cessation of thienopyridine, warfarin and DOAC into the same “discontinuation” group)
Yamamiya et al[122]	2019	Japan	Retrospective	76	Sphincterotomy	Thienopyridine (either continued or ceased 5-7 d or switched to aspirin monotherapy before)	No incidence of PPB in either continuous or cessation group
