P: 95% significance level, Catheter (F/J): Catheter Location Femoral/Jugular, N: Number of catheters, CVVH: Continuous Venovenous Hemofiltration, CVVHDF: Continuous Veno-Venous Hemodiafiltration, IVVHDF: Intermittent Venous-Venous Hemodiafiltration, SCUF: Slow Continuous Ultrafiltration, PP: Plasmapheresis, CVVHD: Continuous Venovenoushemodialysis. Variables expressed as absolute numbers of catheters, median (range), or percentage of catheters used for each indication in at least one connection. Comparisons performed using Mann-Whitney U and Fisher’s exact tests. P value (95% significance level).
