In Butler v. Wong, 117 Ariz. 395, 573 P.2d 86 (App. 1977), the Court held that an expert's inconclusive testimony linking an auto accident to deafness was not alone enough to be considered by the jury but that the testimony could be considered when it also eliminated a possible cause of the injury. See id. at 398-99, 573 P.2d at 89-90.
