missing rxcui ids in rxcui_setid_map table

[inessmit]

I'm using Onsides version 20240925

I notice many rxcui ids that are in the adverse_reactions table but they don't appear in the rxcui_setid_map table.
Examples: 10582 (levothyroxine), 6851 (methotrexate), 1202 (atenolol).

select * from rxcui_setid_map rsm where rxcui in (1202, 10582, 6851);
returns no results

This means that there is no traceable setid to provide a link to the source data of the adverse events in the adverse_reactions table, so the data has no provenance.

However there is data for e.g. levothyroxine in the adverse_reactions table, e.g.
the query

select * from adverse_reactions_active_labels aral 
where aral.ingredients_names like '%levothyroxine%';

returns various results including e.g. setid 73c3d459-dcbf-4458-8edd-2637275a96a1, which is indeed about levothyroxine.
However it's mapped to rxcui 892255 in the rxcui_setid_map table.

select * from rxcui_setid_map rsm where rsm.setid = '73c3d459-dcbf-4458-8edd-2637275a96a1'

Is there be any guidance on how to navigate this?
