Adverse drug reactions are appreciably harmful or unpleasant reactions resulting from an intervention related to the use of medical products, which predicts hazard from future administration and warrants prevention or specific treatment, or alteration of the dosage regimen, or withdrawal of the product. Given medical case reports extracted from MEDLINE, the task is to classify whether the case report mentions the presence of any adverse drug reaction. Classify your answers into non-adverse drug event and adverse drug event.

Example Output: non-adverse drug event

Example Input: Severe systemic cytomegalovirus infections in patients with steroid-refractory ulcerative colitis treated by an oral microemulsion form of cyclosporine: report of two cases.
