^*The numbers are higher than those previously reported,² because they include lung cancers diagnosed at time of death and a later data cut date (January 31, 2011 vs. September 28, 2010).

^†The numbers are higher than those previously reported,² because they result from a later censor date (December 31, 2009 vs. January 15, 2009) and a later data cut date (January 31, 2011 vs. September 28, 2010).

^‡Includes those lost to follow-up before December 31, 2009.
