APPENDIX I.A.1. GUIDELINES DEVELOPMENT METHODOLOGYThe panel has attempted to provide primary care practitioners with recommendations regarding effective strategies to evaluate and treat overweight and obesity in adults. The panel anticipates that the recommendations also will be followed by the large proprietary weight loss industry in the United States. The guideline is based on a systematic review of the scientific literature published in MEDLINE from January 1980 through September 1997. This was done in the interest of time and economy. This information was supplemented by material provided by the panel and a search of appropriate references in eligible articles. The panel identified randomized controlled trials as the strongest level of evidence for the evaluation of treatment efficacy. Thus, evidence from randomized controlled trials (RCTs) serves as the basis for many of the recommendations contained in this guideline. However, in some instances, the panel had to make recommendations in the absence of RCTs. Each evidence statement (other than those with no available evidence) and each recommendation is categorized by level of evidence (A through D) as described in Table A-1.
Statements for which there is no available evidence are so indicated. |
