Table 3. Multivariate clinical prediction models for CCI.

Multivariate clinical prediction models revealed that age ≥ 55 years, systolic hypotension ≤ 70 mmHg, transfusion ≥ 5 units PRBC within 24-hours, and Denver MOF score at 72-hours as independent predictors of CCI.

Model	O.R.	95% C.I.
Baseline (24-hour) model†
Age ≥55	3.7	(1.3, 10.9)
Lowest admission systolic blood pressure ≤ 70 mmHg	4.0	(1.3, 11.6)
PRBC administrated within 24 hours ≥ 5 unit	5.3	(1.7, 16.5)
Denver MOF score at 24 hours	2.9	(1.5, 5.5)
Post resuscitation (72-hour) model††
Age ≥55	3.5	(1.2, 10.4)
Lowest admission systolic blood pressure ≤ 70 mmHg	3.0	(1.0, 9.4)
PRBC administered within 24 hours ≥ 5 units	3.2	(1.0, 9.7)
Denver MOF score at 72 hours	3.0	(1.7, 5.2)

Abbreviations: O.R. = odds ratio; C.I. = confidence interval; PRBC = Packed red blood cells (unit; 300cc) transfusion administered within the fırst 24 hours; MOF, multiple organ failure.
