Yes. The source explicitly frames the question as accidental laboratory leak versus transmission from an infected wildlife mammal, and the quoted sentence says the evidence overwhelmingly favors the lab-leak hypothesis. That is directly about the complete statement and makes the author's stance readily determinable. ([nber.org](https://www.nber.org/papers/w33428?utm_source=openai))

The author is explicitly **for** the statement: the paper sets up lab leak versus natural animal transmission and concludes there is “overwhelming evidence in favor of” an “accidental lab leak,” with an overall odds ratio of 14,900:1. ([nber.org](https://www.nber.org/papers/w33428))

Verified. The NBER landing page for Working Paper 33428 names Andrew T. Levin as the author, gives the issue date as January 2025, and contains the abstract sentence stating that the overall odds ratio is 14,900:1 and favors an accidental lab leak hypothesis. The PDF of the paper reproduces the same sentence in the abstract, so the submitted wording is a faithful mid-sentence excerpt with bracketed omission, not a misattribution or fabrication.
