CAD	2.23 (1.2-4.16)	0.011	1.59 (0.82-2.99)	0.16
PaO2/FiO2 ratio (mmHg)	0.997 (0.99-1.00)	0.09	0.998 (0.99-1.002)	0.51
LAD	1.002 (1.001-1.003)	0.002	1.002 (1-1.003)	0.003

Results are reported as hazard ratio and 95% confidence interval; statistically significant p value < 0.05. HBP, high blood pressure; CAD, coronary artery disease; LAD, lactate dehydrogenase; CRP, C-reactive protein; IL-6, interleukin-6; HR, hazard ratio; CI, confidence interval.

Bold values indicate that the p values are statistically significant.
