Association between Platelet to Neutrophil Ratio (PNR) and Clinical Outcomes in STEMI Patients after Successful pPCI: A Secondary Analysis Based on a Cohort Study

Table 4

The results of two-piecewise linear regression model.

Inflection point of PNR	Effect size (HR)	95% CI	value
<2.31	0.57	0.29 to 1.13	0.1084
≥2.31	1.43	1.16 to 1.75	0.0006

Effect: MACEs. Cause: PNR (per 10-unit change). Adjusted: age, sex, anterior wall myocardial infarction, myocardial infarction history, apelin-12, apelin-12 change rate, LVEDD, peak cTnI, pathological Q wave, Killip grade, FBG, albumin, GENSINI, and eGFR.
