Kaplan-Meier curves for ischemic stroke incidence by neutrophil to lymphocyte ratio levels.

<p>Compared to subjects with NLR<1.5, subjects with 2.5≤NLR<3.0, 3.0≤NLR<3.5, and NLR≥3.5 had elevated risk for ischemic stroke incidence with aHR (95% CI) of 1.76 (1.09–2.84), 2.21 (1.21–4.04), and 2.96 (1.57–5.58), respectively, adjusted for major cardiovascular risk factors. Log-rank test showed P<0.0001.
