"A detailed description of the PBS cohort and protocol has been published recently [] and is also registered at ClinicalTrials.gov (NCT02741674). The study was approved by the institutional review board of Kaiser Permanente Washington Health Research Institute (lead site) and approved or determined to be exempt from review by all participating sites’ institutional review boards. For this analysis, we identified adolescents (age 12–19 yr) who underwent a primary (first) bariatric procedure at health systems affiliated with 11 CDRN (see ) from January 1, 2005 through September 30, 2015. The cohort was identified using the International Classification of Diseases, Ninth Revision (ICD-9), Current Procedure Terminology-4, and Healthcare Common Procedure Coding System procedure codes () extracted from the PCORnet common data model from each site []. Analyses focused on the most common bariatric procedures in the United States (RYGB, SG, and AGB)."
