Lead Authors were required to address the 30 priority questions of the 2022 Scientific Consensus Statement. Questions were addressed using a formal evidence review and synthesis method and delivered by a Lead Author and their team. Selection criteria were established to screen and assess applicants. These criteria included extensive knowledge and experience relevant to the question, a strong publication record in peer reviewed academic literature, and demonstrated experience assembling and leading a team of scientists to deliver technically and scientifically sound products.

To select Lead Authors, a call for Expressions of Interest (EOI) was widely advertised using professional networks and social media channels. Selection criteria were established to screen and assess applicants. These criteria included extensive knowledge and experience relevant to the question, a strong publication record in peer reviewed academic literature, and demonstrated experience assembling and leading a team of scientists to deliver technically and scientifically sound products.

Applicants were asked to complete a standardised form with questions relating to the pre-determined eligibility and selection criteria, and submit an up-to-date CV. A formal Selection Panel with a minimum of three assessors was convened to evaluate the information provided by applicants. Assessors separately scored each applicant against the selection criteria, then met to discuss outcomes and identify applicants to invite as Lead Author for each question. Due to a combination of potential conflicts of interest, science discipline gaps, offers declined, and applicant withdrawals, three EOI rounds were needed before all Lead Authors were appointed.
