As we reviewed our candidate codelist outside openCodelists, we did not benefit from the tree structures that might have identified additional codes. However, we assume that these are likely to be codes that are not used frequently, e.g., eponymous syndromes.\n\n\nRetained codes related to disordered taste/smell (as well as absent taste/smell) as there are reports of continuing change in taste/smell post COVID.\nExcluded all secondary taste/smell disorders, as indicate known cause.\nRetained codes relating to taste loss in anterior/posterior thirds of the tongue, as unclear yet whether taste loss post covid is related to neurological pathology.\n\n",
