Randomized Controlled Trial Multicenter Study
Efficacy and safety of 400 and 800 mg etodolac vs. 1,000 mg paracetamol in acute treatment of migraine: a randomized, double-blind, crossover, multicenter, phase III clinical trial.
We aimed to determine the efficacy and safety of etodolac, in acute migraine attacks in comparison with paracetamol (acetaminophen). ⋯ Our study showed that etodolac is a safe and effective alternative in acute migraine treatment and showed comparable efficacy to paracetamol 1,000 mg. Etodolac may be considered as an alternative option for acute treatment of migraine.

Randomized Controlled Trial Multicenter Study
Relationship of negative affect and outcome of an opioid therapy trial among low back pain patients.
Patients with chronic noncancer pain frequently report symptoms of depression and anxiety (negative affect), which are associated with higher ratings of pain intensity and a greater likelihood of being prescribed chronic opioid therapy. The purpose of this secondary analysis was to test the hypothesis that initial levels of negative affect can predict treatment-related outcomes in a double-blind, placebo-controlled study of extended-release (ER) hydromorphone among opioid-tolerant patients with chronic low back pain. ⋯ Negative affect is associated with diminished benefit during a trial of opioid therapy and is predictive of dropout in a controlled clinical trial.
