A Novel Predictive Model in Recognizing Severe COVID-19 and Multiorgan Injuries: Platelet-to-CRP Ratio

Table 2

Relationship between PC ratio and chest CT performance.

PC ratio tertiles	Chest CT performance
	Crude model		Adjusted model I		Adjusted model II
	OR (95% CI)	value	OR (95% CI)	value	OR (95% CI)	value
1	0		0		0
2	−0.76 (−1.03, −0.49)	<0.001	−0.69 (−0.96, −0.43)	<0.001	−0.51 (−0.78, −0.24)	<0.001
3	−0.89 (−1.15, −0.62)	<0.001	−0.80 (−1.07, −0.53)	<0.001	−0.53 (−0.82, −0.24)	<0.001

Crude model adjusted for none. Adjusted model I adjusted for age, gender. Adjusted model II adjusted for age, gender, hypertension, total protein, albumin, lymphocyte, lactic dehydrogenase, lymphocyte. PC ratio tertile 1 ≤ 7.60; 7.60 PC ratio tertile 2 ≤ 25.44; PC ratio tertile 3 > 25.44.
