Prognostic nomogram for radiomic, clinical, and integrative scores. (a) Prognostic nomogram. The patient’s integrative score, calculated based on the integrative signature of the integrative score axis, was identified. A line was then drawn upward toward the point axis to determine the number of points the patient receives for the integrative score. After repeating the process for the dyslipidemia and age axes, the points achieved for each of the three factors were added. Finally, the total sum of the points on the total points axis was determined, and a line was subsequently drawn straight down to derive the patient’s overall probability of 6-, 12-, and 18-month survival. These points depict the probability of ischemic stroke. (b) Calibration curves of the prognostic nomogram. The curves suggest an acceptable calibration performance for the predicted (x-axis) and actual 6-, 12-, and 18-month stroke occurrence probabilities (y-axis). The diagonal dotted line represents an ideal estimation. This shows a good agreement between estimation and actual observation
