The card lists AEDECOD, AEHLGT, AEHLT, AETERM as spatial axes for ae, but these sound like medical classification terms (adverse event decoded term, high-level group term, etc.) rather than geographic locations. I need to inspect the ae table's columns to confirm whether it has any actual geographic columns like COUNTRY or REGION1, or if the 'spatial axes' are indeed medical classifications.",
