Trial Outcomes & Findings for Carcinogenicity Study of Bupropion (NCT NCT01077596)

NCT ID: NCT01077596

Last Updated: 2017-05-30

Results Overview

The following are the cancers under investigation: colorectal, lung, bladder, uterus, breast, and prostate. Cancer case were nested within a cohort of new antidepressant users. New antidepressant users were defined as no previous antidepressant prescription in the previous 6 months. Cases were identified and matched with controls from the same new-user cohort. Cal year, calendar year; dx, diagnosis; IBD, Inflammatory Bowel Disease; OC, oral contraceptive; HRT/ERT, hormone replacement therapy/estrogen replacement therapy; NSAID, non-steroidal anti-inflammatory drug.
