Animal testing and alternatives
Animal testing and alternatives is a research topic within Small Animals. Science Explorer counts 18k research works in it since 1950. 15.0% of them reached the world's top 10% most cited for their field and year.
This cluster of papers focuses on improving the reporting and conduct of animal research studies, with an emphasis on the use of ARRIVE guidelines, cytotoxicity assays, ethical considerations, systematic reviews, in vitro testing methods, and addressing publication bias. It also discusses the challenges in translating findings from animal studies to human applications and the determination of sample sizes for preclinical studies.
