Box-chart for serum Gly concentrations according to the number of MetS components. Data are depicted by box plots extending from the 25th to the 75th percentile and whiskers ranging from the lower limit to the upper limit. The horizontal line in the box plot represents the median, and dots in the figure represent outliers. MetS and its components were defined based on the 2006 IDF standard. Serum Gly concentrations declined gradually with an increasing number of MetS components (p = 0.03 for trend)
