Figure 9: Gender Percentages: 2005 and 10 Year

Of the 166 cases reported to the registry in 2005, 72% (120/166) were male and 28% (46/166) were female. These data are in keeping with long term trends in the gender distribution of U.S. cases. While the gender ratio can differ dramatically in various areas throughout the world, the 2:1 male/female ratio generally reported for this disease closely approximates that seen over the last 10 years in the U.S.
