Impacts of Subsidized Ridesharing on Drunk Driving, Alcohol Consumption, and Mobility
Summary
The lay summary the sponsor registered on ClinicalTrials.gov.
Investigators
The overall officials registered on this study. Names that resolve to a FindMyKOL profile link to it; the rest are shown as registered.
- Christopher Morrison, PhD
Columbia University
Principal Investigator
A profile link is shown only when the registered name resolves to a person record with a confident, namesake-checked match; ambiguous names stay unlinked.
Sites
1 registered facility, with the per-site recruitment status where the registry publishes one. ClinicalTrials.gov does not publish per-site enrollment counts.
- Columbia University Irving Medical Center

Site investigator names are published by ClinicalTrials.gov only while a study recruits, so completed studies list sites without them.
