The issue focused on medical studies that researchers could study for evidence of neuropsychiatric disorders in research participants.


Problems were identified with scientific literature published between 1998 and 2009. Research scientists reported problems when they provided experiments or investigations that included laboratory animals, biological samples, chemical substances or technologies that may have caused neuropsychiatric disorders. Scientists also noted problems when their experiments involved biomedical engineering studies or experiments involving animal models of diseases or injuries. Scientists found significant difficulties when studies using experiments from laboratories outside the United States had
