There was a statistical trend towards lower mortality in the filter group (6.7 [ n = 27] vs. 4.0 % [ n = 16], control vs. filter group; P = 0.09).
There was a statistical trend towards lower mortality in the filter group (6.7 [ n = 27] vs. 4.0 % [ n = 16], control vs. filter group; P = 0.09).
Although there were reductions in the incidence of sepsis, ARDS, circulatory failure, thrombosis, acute liver and acute renal failure in the filter group, these differences did not reach statistical significance (Table 2 ; Fig. 2 ).
