  1. *Analysis only counted each patient’s first qualifying catheter insertion; Duration of catheter placement = time from catheter insertion to first qualifying outcome event, catheter replacement or removal, health plan termination, or study end.
  2. CVC, central venous catheter; HD, hemodialysis; IQR, interquartile range; SD, standard deviation.
