Distribution of NLR and PLR According to Pulmonary Embolism Severity.^a

Parameter	Low Risk PE, n = 61	Submassive PE, n = 117	Massive PE, n = 13	P Value
NLR	4.18 (2.58-6.69)	4.46 (2.58-8.55)	2.88 (1.71-8.79)	.58
PLR	173 (109-145)	154 (96.0-250)	90.3 (50.4-164)b	.02

Abbreviations: IQR, interquartile range; NLR, neutrophil-to-lymphocyte ratio; PE, pulmonary embolism; PLR, platelet-to-lymphocyte ratio.

^a Values are expressed as median (IQR).

^b P < .01 versus low-risk PE.
