When do I know I am cured? Using conditional estimates to provide better information about cancer survival prospects

Incorrect confidence intervals: In “When do I know I am cured? Using conditional estimates to provide better information about cancer survival prospects” in the 17 January 2011 issue of the Journal (Med J Aust 2011; 194: 73-77), there were several minor errors in the 95% confidence intervals given in Box 1: Conditional 5-year relative survival estimates, by type of cancer and number of years after diagnosis, for patients aged 15–89 years at diagnosis, Queensland 1998–2007. These errors applied to survival estimates for stomach cancer, pancreatic cancer, lung cancer, kidney cancer, bladder cancer, non-Hodgkin lymphoma and leukaemia. The 95% CIs have been corrected in the online version of the article, and can be seen at: http://www.mja.com.au/public/issues/194_02_170111/baa10523_fm.html.
