Table 1

Comparison of the clinical characteristics and prognostic scores of the groups of patients in the study.

Age (years), mean (SD)	67.9 (18.8)	71.5 (18.0)	64.2 (19.2)	0.127
Masculine, N (%)	33 (53.2)	15 (48.3)	18 (58.0)	0.305
BMI, mean (SD)	27.6 (4.8)	27.1 (4.1)	28.0 (5.5)	0.496
Braden, mean (SD)	10.8 (1.7)	10.8 (1.7)	10.9 (1.7)	0.884
SAPS 3, mean (SD)	69.4 (14.9)	70.8 (15.2)	67.9 (14.7)	0.444
SOFA, mean (SD)	8.3 (4.2)	8.4 (4.5)	8.2 (3.9)	0.834
LOS ICU (days), median (ITQ)	11.5 (7.5–22.0)	15.0 (8.5–23.5)	10.0 (4.5–22.0)	0.152
LOS hospital (days), median (ITQ)	18.5 (10.5–29.0)	22.0 (14.5–37.5)	15.0 (8.5–25.0)	0.036

Group 1 = pyramidal; Group 2 = viscoelastic; ITQ: interquartile range; BMI: body mass index; SD: standard deviation; ICU: intensive care unit; SAPS 3: simplified acute physiology score; SOFA: sequential organ failure assessment; LOS: length of stay. Student’s t-test; chi-squared test; Mann–Whitney test.
