Medical research results obtained in animal studies may not be the same as results obtained in human studies.
Is it true that medical research results obtained in animal studies may not be the same as results obtained in human studies?
Yes. Medical research findings obtained in animal models frequently fail to translate directly to humans due to significant physiological and species-specific differences.
Verdict: SUPPORTED · 7 sources for, 0 against · Last checked
The retrieved literature extensively documents the translational crisis in biomedical research, emphasizing that results and therapeutic efficacy observed in animal studies often do not replicate in human clinical trials due to species differences.
