An example of how to use the nomogram to predict chance of HT after thrombolysis. In this example, we calculated the predicted probability of HT in a patient with hypertension, a NIHSS score of 5, the total CSVD burden score of 3, and the OTT time greater than 180 min. Points are assigned for each feature: 33 for the CDS score of 1, 72 for the total CSVD burden score of 3, 46 for OTT time greater than 180 min, and 0 for NIHSS score of 5. The total of 151 points corresponds to a nearly 13.7% chance of HT after thrombolysis for this patient.The formula for calculating probability of HT is provided in the data supplement. Abbreviations: CDS: chronic disease scale (hypertension, diabetes mellitus, atrial fibrillation); CSVD: cerebral small vascular diseases; NIHSS: National Institutes of Health Stroke Scale; OTT: onset-to-treatment time for thrombolysis
