Restricted mean survival time asymptotics
WebAug 24, 2015 · The RMST is the mean survival time of all subjects in the study population followed up to t, and is simply the area under the survival curve up to t. The advantages of using such a quantification over the survival rate have been discussed in the setting of a fixed-time analysis. Webthe former does not include information on survival status. The mean survival time can be estimated by calculating the area under the survival curve (incorporating both survival status and time) of the survival function up to infinity. If there are no censored observations, the mean survival time can be used. However, if the last observation

WebIf the last observation(s) is not a death, then the survival curve estimate does not go to zero and the mean survival time cannot be estimated. Instead, the quantity reported is the mean of survival restricted to the time before the last censoring. When the last censoring time is not random this quantity is occasionally of interest. WebAug 8, 2016 · The aim of this article is to summarize the role of restricted mean survival time (RMST) analysis in oncology. Everyone is familiar with the use of median survival, or more generally with median time to event (where the event could be progression or treatment failure), to summarize long-term patient outcome.
