I want to find patients with acute upper respiratory infections of multiple or unspecified sites who have experienced cough symptoms at any time, with a specificity scale of 0 and a panel accuracy scale of 100, with the diagnosis code constrained by date. The query will include two items: one for cough symptoms and another for acute upper respiratory infections, both with a high level of specificity (hlevel = 3) and no synonyms. The query will have a total of two item occurrences, with the first item focusing on cough symptoms and the second item focusing on acute upper respiratory infections of multiple or unspecified sites.
