Observational evidence in humans from several databases support this finding; however, a recent study has suggested that tamsulosin, the comparator medication, increases risk of Parkinson’s disease. We consider a different comparison group of men taking 5α-reductase inhibitors as a new, independent comparison allowing us to both obtain new estimates of the association between TZ/DZ/AZ and Parkinson’s disease outcomes and validate tamsulosin as an active comparator. Methods Using the Truven Health Analytics Marketscan database, we identified men without Parkinson’s disease, newly started on TZ/DZ/AZ, tamsulosin, or 5α-reductase inhibitors. We followed these matched cohorts to compare the hazard of developing Parkinson’s disease. Results We found that men taking TZ/DZ/AZ had a lower hazard of Parkinson’s disease than men taking tamsulosin (HR=0.72, 95% CI: 0.66-0.78, n=239,946) and lower than men taking a 5α-reductase inhibitors (HR=0.81, 95% CI: 0.72-0.92, n=129,320). The hazard for men taking tamsulosin was not statistically significantly different than for men taking 5α-reductase inhibitors (HR=1.10, 95% CI: 1.00-1.22, n=157,490). Conclusions These data suggest that men using TZ/DZ/AZ have a lower risk of developing Parkinson’s disease than those using tamsulosin or 5α-reductase inhibitors while users of tamsulosin and 5α-reductase inhibitors have relatively similar survival functions.","journal":"medRxiv","year":2022,"id":306902,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":0,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9613,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2022-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":401889,"name":"Michael J.
