Notes: All estimates (% and totals) are weighted to be nationally representative for the commercially insured population with continuous enrollment. Individuals were considered to have been co-dispensed naloxone if an opioid claim and naloxone claim were within 7 days of each other. t-Tests were conducted to test for statistical significance.
