Survival by Race and Ethnicity in Children and Adolescents/Young Adults With Relapsed/Refractory Hodgkin Lymphoma: A Pooled Analysis of Children's Oncology Group Trials

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Despite 5‐year survival rates of over 90% among children and adolescents/young adults (CAYAs) with classic Hodgkin lymphoma (cHL), 15%–20% relapse after frontline therapy. Prior analysis of frontline Children's Oncology Group (COG) clinical trials demonstrated that, despite similar rates of relapse, non‐Hispanic Black (NHB) and ...

Models as Documents, Documents as Models

open access: yes, 2022
In software engineering, documentation and models are both broad concepts which attract varying approaches and attitudes. Moreover, as the title indicates, they overlap: in some circumstances, an artefact thought of as a model can serve to document a software project, while in others, an artefact thought of as a document can be manipulated by model ...
