*All data were statistically significant at the P < 0.001 across groups, except for cells marked with a note indicating otherwise

†Not significantly different across groups

Follow-up opioid defined as any opioid prescription within the 2-year follow-up period. SD standard deviation, MED morphine equivalent dose, NS not significant
