dBP pre-HD diastolic pressure pre-hemodialysis, iPTH intact parathyroid hormone, sBP pre-HD systolic blood pressure pre-hemodialysis
Model 1: including age, sex, sBP pre-HD proximate the onset, corrected serum calcium
Model 2: in addition to the model 1’s parameter, antiplatelet use was selected by stepwise method (mixed method)
