Platelet-to-neutrophil ratio predicts hemorrhagic transformation and unfavorable outcomes in acute ischemic stroke with intravenous thrombolysis

Figure 1 Receiver operating characteristic curve. A: Receiver operating characteristic curve (ROC) of platelets to neutrophil ratio (P/NR) for predicting 90-d outcome in acute ischemic stroke after intravenous recombinant tissue plasminogen activator (rtPA); B: ROC of P/NR for predicting delay neurological deterioration in acute ischemic stroke after intravenous rtPA; C: ROC of P/NR for predicting hemorrhagic transformation in acute ischemic stroke after intravenous rtPA; D: ROC of P/NR for predicting early neurological deterioration in acute ischemic stroke after intravenous rtPA.
