Prevalence of chronic pain in Brazil: A systematic review and meta-analysis.

Objective: This review synthesized existing studies on the prevalence of chronic pain in Brazil and its associated factors to produce a recent estimation to guide public health politics.

Methods: A search was carried out in the Ovid Medline, Embase, Web of Science, and BVS Regional/Lilacs databases to identify population-based cross-sectional studies from 2005 to 2020, which reported the prevalence of benign chronic pain in Brazil (more than three months). The risk of bias was assessed using design, sample size determination, and random selection as essential issues.

The parasitological data were complemented with the assessment of the plasma disposition kinetics of IVM. The trial included two different experiments.
