Waiver policy: Authors from low-income countries, as classified by the World Bank, and authors who demonstrate financial hardship may apply for a full or partial waiver by email to the Editor-in-Chief at submission. [State waiver criteria and percentage.] Waiver requests are decided independently of the editorial review.
