- Addition of Number Needed to Treat and Number Needed to Harm for each medication option
- Addition of the most common side effects for all options, and side effect comparison notes amongst medications in the TCA and SNRI classes
- Evidence-based guidance on combination drug therapy options
- Addition of several new medication options beyond first-line choices: opioids (tramadol, tapentadol, morphine, oxycodone, hydromorphone); and for the US: topical analgesic patches (capsaicin and lidocaine) and extended-release formulations for gabapentinoids
