Ref.	Year	Country	Study design	n	Procedure	Medication	Relative risk
Paik et al[137]	2018	South Korea	Retrospective	96	Sphincterotomy	Warfarin with HBT	Incidence of delayed PPB 7.3%
Muro et al[138]	2020	Japan	Retrospective	149	Sphincterotomy	Warfarin either: (1) Continued; (2) With HBT	Incidence of PPB 8.3% (warfarin continued). Incidence of PPB 4.0% (with HBT)
Yamamiya et al[122]	2019	Japan	Retrospective	76	Sphincterotomy	Warfarin: (1) Continued; (2) With HBT	No incidence of PPB in either continuous or HBT group
