What is the test for reversing an evidentiary ruling in a personal injury case?

We review evidentiary rulings for abuse of discretion and will reverse only for "manifest error." Cameron v. City of New York, 598 F.3d 50, 61 (2d Cir. 2010) (internal quotation marks and alteration omitted). We afford district courts "wide latitude in determining whether evidence is admissible." Id. (internal quotation marks omitted). Furthermore, even if there is manifest error, we will not reverse if the error was "harmless." Id. (internal quotation marks omitted). An error is harmless if we "can conclude with fair assurance that the evidence did not substantially influence the jury." Id. (internal quotation marks omitted).
