I want to find patients with hyperglycemia (high blood sugar levels) within the last 20 hours and 45 minutes, specifically those who were diagnosed between 17 minutes and 17 hours ago. This query is a subpanel of the main panel "18--Hyper-HMG-C@20:16:19", and I would like the results to be as accurate as possible.
