Figure 1.

Panel A shows the percentage of opioid use disorder–related index events that were followed by receipt of any filled prescription for buprenorphine within 180 days, according to quarter (Q) from the second quarter of 2016 through the second quarter of 2019 and according to race of the beneficiary. Panel B shows the same for filled prescriptions for naloxone. I bars indicate 95% confidence intervals, under an assumption of a normal approximation.
