As a CTS participant, you are welcome to use the CTS graphs for research and teaching purposes. Permission must be obtained for the use of CTS graphs for publication in printed form. Commercial use is not allowed. Please consider that the graphs are presenting a compilation of results submitted to CTS, without further scientific analysis (e.g. Cox regression, etc.). As such, the data are to be considered preliminary. Consequently, p values are not provided with the graphs.
Each graph is identified by the code shown below the border on the lower right side. For citation of CTS data from the website, please be sure to include the month and year of the identification code (e.g. "CTS-K-11101-Dec2001", "K-11101-1201").
