Figure 2. Mean Days Supplied in the Initial Postoperative Prescription Before and After Opioid Legislation in Massachusetts and Connecticut.

Figure 2.

A, In Massachusetts, implementation of the limit was associated with an immediate level decrease in days supplied (−0.4 days [95% CI, −0.6 to −0.2 days]) but no significant slope change (0 d/mo [95% CI, −0.02 to 0.02 d/mo]). B, In Connecticut, implementation of the limit was not associated with a significant immediate level change in days supplied (−0.3 days [95% CI, −0.7 to 0.1 days]) or slope change (0 d/mo [95% CI, 0-0 d/mo]).
