University of Nebraska Medical Center officials say it's unusual for the integrity of a research study to be questioned, but they don't know yet if there is a problem.
Sheila Wrobel is chief compliance office at the University of Nebraska Medical Center. She says the 60-day inquiry that began in late July will determine whether a full investigation is warranted.
The initial inquiry could also confirm the validity of the research.
Wrobel says the university has an obligation to check out the allegations and make sure the science is valid.
The American Journal of Respiratory and Critical Care Medicine raised questions about a study it published online in February. The study was done jointly by UNMC and researchers from Temple University School of Medicine in Philadelphia.
