Development and Validation of a Dynamic Prediction Model for Massive Hemorrhage in Trauma

Figure 3

The web calculator for the dynamic prediction models for a future massive hemorrhage in trauma. (a) Data entry page; (b) forecast results page. Click the ‘Click to download’ link in Figure 3(a) to download the excel template, import the vital signs time-series data according to the template format, click the ‘SELECT FILE’ button to select the file to be uploaded, and finally, click the “CALCULATE” button for risk prediction. The imported vital signs time-series data are shown at the top of Figure 3(b), and the prediction probability of massive hemorrhage in trauma in the future 1, 2, and 3 hours is shown below, in the range of [0, 1]. The higher the value, the greater the risk of massive hemorrhage.
