Oxford Analgesic League Table

Single dose analgesics for moderate to severe acute pain: NNT* for at least 50% maximum pain relief over four to six hours.

* NNT (number needed to treat). The number of patients needed to be treated for one to benefit compared with a control. A treatment that works for everyone, and where no patient has a response with control would have a NNT of 1. The higher the NNT, the less effective the treatment.  Treatments with NNTs of 2-5 are considered effective for acute pain.
