We study the problem of testing multiple secondary endpoints conditional on a primary endpoint being significant in a two-stage group sequential procedure, focusing on two secondary endpoints. This extends our previous work with one secondary endpoint. The test for the secondary null hypotheses is a closed procedure.

Objectives: The authors hypothesized that posttraumatic stress disorder (PTSD) and HIV interact to contribute to ED in WWH.
Management of Anomalous Left Vertebral Artery During Open Total Arch Replacement.
Ann Thorac Surg Short Rep
December 2024
Background: An anomalous left vertebral artery (aLVA) can complicate aortic arch surgery. We examined the safety of various aLVA revascularization strategies during open total arch replacement.
Methods: We retrospectively evaluated 92 patients undergoing total arch replacement from January 2018 to May 2023 and identified 11 patients with aLVA.
Background: Given their importance as a metric for health care evaluation, this study's aim was to evaluate the rates of surgical and catheter reinterventions for children with functionally single-ventricle (f-SV) congenital heart disease (CHD) undergoing staged palliation.
Methods: We undertook a retrospective cohort study of children born with f-SV CHD between 2000 and 2018 in England and Wales, using the national registry, with survival ascertained in 2020. Competing risk analysis was used to describe the incidence of additional procedures that occurred first, during follow-up, accounting for competing events of death or transplantation.
