The analysis showed a positive association of adopting the Paleolithic diet in relation to weight loss .
Conclusion The Paleolithic diet may assist in controlling weight and waist circumference and in the management of chronic diseases .
Background The Paleolithic diet has been studied in the scope of prevention and control of chronic noncommunicable diseases ( CNCD ) .
The objective of this study was to analyze the influence of the Paleolithic diet on the prevention and control of CNCD in humans , specifically on anthropometric markers , through a systematic review with meta- analysis .
Methods What is the effect of the Paleolithic diet on anthropometric parameters ( weight , body mass index and waist circumference ) compared to other control diets based on recommendations in adults ?
GRADE guidelines: 3. Rating the quality of evidence.
This article introduces the approach of GRADE to rating  quality of evidence .  GRADE specifies four categories-high , moderate , low , and very low-that are applied to a body of evidence , not to individual studies . In the context of a systematic review , quality reflects our confidence that the estimates of the effect are correct . In the context of recommendations , quality reflects our confidence that the effect estimates are adequate to support a particular recommendation . R and omized trials begin as high- quality evidence , observational studies as low quality . " Quality " as used in GRADE means more than risk of bias and so may also be compromised by imprecision , inconsistency , indirectness of study results , and publication bias . In addition , several factors can increase our confidence in an estimate of effect . GRADE provides a systematic approach for considering and reporting each of these factors . GRADE separates the process of assessing quality of evidence from the process of making recommendations . Judgments about the strength of a recommendation depend on more than just the quality of evidence
