Chronic postsurgical pain (CPSP) is one of the most common and severe complications after surgeries, and it may seriously impact patients' quality of life and well-being. Although several risk factors were identified for CPSP, the mechanisms of CPSP development remain unclear. This study aims to identify single-nucleotide polymorphisms associated with CPSP development after one of the most common types of surgery: abdominal surgery. This archive is intended to store the summary statistics of Genome-Wide Association Studies (GWAS) for CPSP following abdominal surgeries.
