Dear Collaborators,

We are pleased to share with you Causes of Death (CoD) preliminary estimates for GBD 2020. Reviewing preliminary estimates is an opportunity available exclusively to GBD Collaborators. This is your chance to review the levels and trends for causes or countries that interest you, and to inform us of any major concerns.
 
Please note that the deadline for sending comments is Friday, June 12, 2020 at 11:59pm PDT.

 Thank you in advance for your time and effort at this important stage.

I. Reviewing the Preliminary Estimates
To enable you to share feedback as efficiently and easily as possible, we have framed two critical questions regarding these estimates. We would greatly appreciate your feedback on these questions:

1. Based on your expertise in a country or location, are there cases where the level or trend of mortality due to a specific cause does not match the data or the epidemiological profile of the country/location?
2. Are there data sources we have included that should be marked as outliers (due to unreliable data collection, unrepresentative samples, or other concerns)?

• For reference, the GBD Cause list of fatal causes can be accessed here.

• New locations added for GBD 2020. For this round of GBD, the location changes included were limited to Norway subnationals, where estimates have been updated to reflect the merging of select subnational locations.
• Addition of new data sources
• New age groups

• Updates to cause-specific modeling methods
• Addition of new causes
• New data processing methods for both new and previous data sources

What about COVID19?
We know there is great interest in the estimation of the burden due to COVID19. In GBD 2020, estimates for both fatal and non-fatal outcomes for COVID19 will be computed. As COVID19 is a new cause in GBD 2020, we are still working to incorporate it into our estimation which is why you do not see them in this set of preliminary results.

Lastly, please note that you are receiving privileged access to these preliminary results as a GBD collaborator; these results are confidential and should not be cited or circulated.

Thank you again for your collaboration. We look forward to improving these results with your help.
