Letter to the Editor: "Pediatric Obesity-Assessment, Treatment, and Prevention: An Endocrine Society Clinical Practice Guideline"

We read with interest the recently published clinical practice guidelines for preventing and treating childhood obesity (1). The authors reported their evaluation of the quality of the evidence and an assessment of the strength of recommendations according to objective criteria across a diverse literature. In our view, however, this excellent and comprehensive report does not mention two relevant issues: attrition and enrollment. These issues are likely to be of concern for clinicians, administrators, and researchers because they can have a substantial impact on clinical care.
