Review Meta Analysis
Adverse events attributable to nocebo in randomized controlled drug trials in fibromyalgia syndrome and painful diabetic peripheral neuropathy: systematic review.
The objectives of the study were to determine the impact of nocebo effects on adverse events (AEs) in drug trials in fibromyalgia syndrome (FMS) and painful diabetic peripheral neuropathy (DPN). ⋯ Nocebo effects substantially accounted for AEs in drug trials of FMS and DPN. Standards to assess and report AEs should be defined by regulatory agencies. Strategies to minimize nocebo effects in both clinical trials and clinical practice should be developed.

Review Meta Analysis
Transcranial direct current stimulation for the reduction of clinical and experimentally induced pain: a systematic review and meta-analysis.
To evaluate the effectiveness of transcranial direct current stimulation on clinical and experimental pain, and to identify the most beneficial stimulation parameters. ⋯ The level of evidence for the efficacy of transcranial direct current stimulation in experimental and chronic pain reduction is low. Evidence from high quality randomized controlled trials is required before this treatment should be recommended.
