Treatment times of patients receiving CVVHD (a) or SLEDD (b). Circles show mean duration of treatment according to anticoagulant regimen. Error bars depict SEM. P-values were calculated using a two-tailed student’s t-test comparing the CVVHD-subgroups and ANOVA with Tukey’s multiple comparisons test comparing the SLEDD-subgroups. Dashed lines represent minimal expected treatment times (48 h for CVVHD, 10 h for SLEDD)
