This article separates the medical tourism narrative from what actually matters for site selection, and looks at how Renova Clinical Trials, based in Tijuana, operates within that

How physician-led oversight affects data quality, safety, and protocol compliance — and what it looks like in practice at Renova Clinical Trials, a physician-led research site in the San Diego–Tijuana corridor.
