   “Cost-effectiveness models for GiveWell's Top Charities can be accessed via the links below: - Malaria Consortium's Seasonal Malaria Chemoprevention Program - Against Malaria Foundation - Helen Keller Intl's Vitamin A Supplementation Program - New Incentives”

2. E2 2021 Cost-Effectiveness Analysis Changelog GiveWell · 5 May 2021 Own record

   “Our leverage and funging adjustments for AMF are calculated on a non-public spreadsheet. We have not made this spreadsheet publicly available because we have not received permission to publish country-specific cost estimates we received from the Global Fund to Fight AIDS, Tuberculosis and Malaria, which our calculations rely on.”

3. E3 2021 Cost-Effectiveness Analysis Changelog GiveWell · 28 September 2021 Own record

   “Link to the cost-effectiveness analysis (CEA) file: 2021 CEA — version 3”

4. E4 Process for Identifying Top Charities GiveWell · July 2025 Own record

   “we publish the details of our analysis, spell out our major assumptions and allow readers to fill in their own.”

GiveWell's 2021 changelog links to a published CEA workbook (version 3, dated 28 September 2021), which shows its top-charity cost-effectiveness analyses were posted on its website before April 2022 [E3]. The same changelog states that the leverage and funging adjustments for the Against Malaria Foundation were calculated on a non-public spreadsheet because of third-party data restrictions, so at least one component was not public [E2]. E1 and E4 describe the practice of publication, but they reflect later page versions and come from the subject itself. All the evidence comes from GiveWell, but E3 is the published output itself; on that basis, most analyses were public with a notable exception.
