To the Editor: In their randomized trial of femoral vs jugular venous catheterization and nosocomial events in adults requiring acute renal replacement therapy, Dr Parienti and colleagues1 noted thrombotic events in the analyzed groups. It is unclear whether these events were precipitated by the catheters or occurred secondary to the multiple risk factors in the study population.
