A successful HD session is defined in terms of efficacy of the drug where the HD session had completed as planned: there was no premature termination due to Grade 3 or 4 clotting or saline flush to prevent the loss of the extracorporeal circuit due to clotting; it was not possible to return the participant's blood or assess the exact extent of clotting. HD sessions which terminated prematurely due to Grade 1 or 2 clotting, safety event, machine failure, or access site displacement were excluded from the analysis. The point estimate and 95% CI were computed based on generalized estimating equation (GEE) model for clustered binomial data.

Major hemorrhages: defined as fatal bleeding, clinically overt bleeding causing a fall in hemoglobin greater than or equal to 20 gram (g)/litre (L) (2 g/ decilitre \[dL\]), clinically overt bleeding leading to transfusion of greater than or equal to 2 units of whole blood or red cells, or symptomatic bleeding in areas of special concern (intracranial, retroperitoneal, intraocular, intraspinal, pericardial, intramuscular with compartmental syndrome, or intraarticular). Minor hemorrhages: defined as bleeding that did not meet the definition of major bleeding.

Minor hemorrhages: defined as bleeding that did not meet the definition of major bleeding.

Clinically relevant minor (non-major) bleeding was defined as any bleeding compromising hemodynamics, leading to hospitalization, subcutaneous haematoma more than 25 cm\^2, intramuscular haematoma, epistaxis lasting for more than 5 minutes, spontaneous gingival bleeding, macroscopic hematuria and gastrointestinal hemorrhage (including at least 1 episode of melaena or hematemesis), rectal blood loss, hemoptysis, and any other bleeding with clinical consequences.

Trivial bleeding was defined as all minor bleeding that did not meet the definition of clinically relevant minor bleeding.

University of Texas (UT) system assesses ulcer depth, wound infection and clinical signs of lower-extremity ischemia. UT Wound Classification (1C/2C) was based on grade (0= healed site to 3= penetrating wound to bone or joint) and stage (A= clean wounds to D= ischaemic infected wounds) of wounds. Participants were evaluated at 4 stratums: Stratum 1: Toe pressure\>30 mm of mercury (mmHg) and UT grade and stage 1C. Stratum 2: Toe pressure\<=30 mmHg and UT grade and stage 1C. Stratum 3: Toe pressure\>30 mmHg and UT grade and stage 2C. Stratum 4: Toe pressure\<=30 mmHg and UT grade and stage 2C.
