Figure. Monthly Trends in Buprenorphine Initiation and Retention in the US, January 2016 Through October 2022.

Figure.

A, Monthly number of patients initiating buprenorphine therapy per 100 000 US individuals. Vertical blue dotted line denotes a slope change detected by joinpoint regression. B, Monthly 180-day rate of retention among patients initiating buprenorphine therapy. Analyses of retention stopped in April 2022 owing to the need for a 180-day look-forward period to assess retention. No slope change in the rate of retention was detected by joinpoint regression.
