Thanks Ali! Ok if I make another PR into this one to explain a bit more above the note you added?

.. note::

As of March 2025 it is undecided whether the hemoglobin risk factor will be included in the GBD 2023 publication. Regardless, risk effects estimates for the following affected outcomes have been uploaded to GBD shared functions.
The low hemoglobin risk factor was NOT included in the GBD 2023 risk factors capstone publication (release ID 16). However, estimates specific to the low hemoglobin risk factor that were used to inform the low hemoglobin burden of proof publication are available within release ID 33 (`see details here <https://hub.ihme.washington.edu/spaces/GBDdirectory/pages/171583888/Releases+rounds+and+versioning>`__). Release ID 33 should be used to pull all data related to the low hemoglobin risk factor -- note that release ID 16 may return data, but it is expected to be outdated.

Does this mean we need to change this?

Oof, good question... I was really thinking about "risk effects" rather than "risk factor" when I wrote this. I just checked the exposures between release IDs and the values are the same to 2 decimal places but not exactly the same beyond that for the age/sex/location group I looked at. I think if we were using the GBD PAF values in our sim then it would be best to use release ID 33 for exposure. However, since we are planning to calculate our own PAFs, I actually think it is preferrable to use release ID 16 to be most consistent with the exposure that was used for calculation of anemia YLDs in GBD 2023 (which is release ID 16). it looks like they are nearly identical so it won't make much of a difference anyway. The values that have large discrepancies between release IDs and therefore pretty important to get release ID correct are the RRs.
