Web-based dynamic nomogram for prediction 5-year all-cause mortality probability. By entering the specific information of the older adult with hypertension in the web-online tool, we could obtain the participant’s corresponding 5-year all-cause mortality probability. A Entering Interface: You can enter the specific information of the participant in this interface. B Graphical Summary: The 5-year all-cause mortality probability and 95% confidence interval of participants are depicted in this interface. C Numerical Summary: The actual values of 5-year all-cause mortality probability and 95% confidence interval are shown in this interface
