Percentage of men stratified to low-, intermediate-, and high-risk groups in each year group. Patients designated as “Int/High” are those stratified to high risk using the standard definition (including T2c) and intermediate using the more restrictive definition (T3a only) of high risk. Numbers indicate aggregate totals for each group in each time period: 1990-1994, 1995-1999, 2000-2001, 2002-2003, and 2004-2007. The trend toward more low- and less high-risk disease at diagnosis was significant (P<0.001).
