Fig 3. Changes in NIHSS scores from admission to follow-up for patients, displayed in a relative-frequency histogram. Black bars indicate patients who received IV rtPA but no endovascular intervention. Gray bars indicate patients who received IV rtPA followed by endovascular intervention. Patients who worsened after admission have negative scores (toward the left), whereas patients who improved have positive scores (toward the right). Improvement in NIHSS scores is significantly higher in patients who received IV rtPA plus an endovascular intervention (P = .025).
