Figure:. Kaplan-Meier Curve Evaluating Time to Death by AI-Risk Category and Receipt of Aortic Valve Replacement Among Individuals with Severe Low-gradient Aortic Stenosis
Displayed is a Kaplan Meier curve demonstrating the proportion of individuals without an event (death; y-axis) according to time in years (x-axis) from the index echocardiogram by machine-learning (ML) designated risk group and receipt of aortic valve replacement (AVR). The red curve indicates individuals determined to be higher-risk by the ML algorithm who received an AVR in follow-up, the green curve indicates individuals determined to be lower-risk who received an AVR, the blue curve indicates individuals at higher-risk who did not receive an AVR, and the orange curve indicates individuals at lower-risk who did not receive an AVR. Numbers in the risk set are provided below at 1-year intervals. The log-rank p-value for comparison across groups was <0.001.
