However, the NCEP-ATP III and IDF definitions have been found to show good agreement in the diagnosis of MetS.[42], [43] Additionally, BMI has been suggested as equally effective as waist circumference for predicting the development of metabolic disorders[44], [45] and has been adopted in previous studies of the MetS.[1], [46] We were also unable to correct the estimates for within-individual variation in levels of ALT over time which may have underestimated the associations, because data involving repeat measurements were not reported by the contributing studies. This evidence concerns the gene GPT and Other metabolic disease.
