CONCLUSIONS The use of an additional drape reduced radiation exposure of both the first and second operator during routine radial procedures; a shield-attached curtain alone was only partially effective.Composite endpoints are commonly used in clinical trials, and time-to-first-event analysis has been the usual standard. Time-to-first-event analysis treats all components of the composite endpoint as having equal severity and is heavily influenced by short-term components. Over the last decade, novel statistical approaches have been introduced to overcome these limitations. We reviewed win ratio analysis, competing risk regression, negative binomial regression, Andersen-Gill regression, and weighted composite endpoint (WCE) analysis. Each method has both advantages and limitations. The advantage of win ratio and WCE analyses is that they take event severity into account by assigning weights to each component of the composite endpoint. These weights should be pre-specified, because they strongly influence treatment effect estimates. Negative binomial regression and Andersen-Gill analyses consider all events for each patient - rather than only the first event - and tend to have more statistical power than time-to-first-event analysis. Pre-specified novel statistical methods may enhance our understanding of novel therapy when components vary substantially in severity and timing. These methods consider the specific type of patients, drugs, devices, events, and follow-up duration.AIMS This study evaluated the optical frequency domain imaging (OFDI) artifact of tangential signal dropout (TSD), which mimics the appearance of lipid-rich plaque and macrophage (Mø) infiltration. METHODS AND RESULTS A total of 1,019 histological cross-sections from 23 autopsy hearts were matched with the corresponding OFDI images. Of those, 232 OFDI cross-sections that contained signal-poor regions with diffuse borders were classified
