Errors in this meta-analysis have been noted: [PMID:32348451]; the authors state that the corrections do not affect their conclusions [PMID:32348461] and that, as of July 2020, they were republishing the article [PMID:32666106].
Meta analysis of 8 studies: [PMID:30050374], [PMID:27223304], [PMID:25828624], [PMID:25349058], [PMID:24473459], [PMID:25304296], [PMID:19604407], and [PMID:17583796]. Paleo diets were not defined by the authors of the meta-analysis; control diets included Dutch, Nordic, and Australian healthy eating guidelines, conventional diabetes diets, a Mediterranean-like diet, or the participants' usual diet. Duration ranged from 2 weeks to 24 months (but outcomes at 6 months were used for the analysis if the study lasted longer). Quality of studies was mostly good, as determined with the Cochrane Collaboration Risk of Bias Tool.
