Line graph showing the association of the metabolic syndrome (MetS) with lower urinary tract symptoms (LUTS). LUTS severity, on a scale of 0 to 35, is plotted on the X axis. MetS prevalence is plotted on the Y axis. The graph designates no symptoms as total LUTS scores from zero to 1, mild symptoms as total LUTS scores from 2 to 7, moderate symptoms as LUTS scores from 8 to 19, and severe symptoms as LUTS scores from 20 to 35. According to the graph, only about 20 percent of men without LUTS had MetS, but 30 percent or more of men with mild, moderate, and severe LUTS had MetS.
