1. Survival estimates of patients in REVEAL using Kaplan–Meier estimates stratified by newly versus previously diagnosed patients and survival estimated by a delayed entry model accounting for truncation.
Survival estimates of patients in REVEAL using Kaplan–Meier estimates stratified by newly versus previously diagnosed patients and survival estimated by a delayed entry model accounting for truncation. The model includes all REVEAL patients but the number of patients at risk is limited to the time period during which they were followed in the study. Therefore, the first 3 months is estimated exclusively based on newly diagnosed patients and thereafter combined data from previously diagnosed patients and long-term follow-up of newly diagnosed patients. #: newly diagnosed; ¶: previously diagnosed.
