I want to find patients who have been diagnosed with asthma (JGOG-Asthma@18:24:56) during the same visit as when they were prescribed prednisone or prednisolone (medications, hormones, adrenal cortical steroids). The specificity scale is set to 0, indicating that any occurrence of the mentioned condition or medication is relevant, and the panel timing is set to SAMEVISIT, meaning the condition and medication must be present during the same visit. The accuracy scale for each panel is set to 100, indicating that the query is highly accurate. The total number of items in the first panel is 1, which represents the asthma diagnosis, and the total number of items in the second panel is 2, representing prednisone and prednisolone. The invert parameter is set to 0, meaning the query will return only positive results.
