Cancer Among Potash Workers in Saskatchewan: Erratum

Fig. 1 in the following manuscript published in JOEM was incorrect: Pahwa P, McDuffie H. Cancer among potash workers in Saskatchewan. J Occup Environ Med. 2008;50:1035–1041.

Fig. 1.: Cancer-free survival probabilities by smoking status and presence of any respiratory disease.

The figure itself was rendered properly, but the y- and x-axes labels and the legend were not. The correct figure appears here.

This error has been noted in the online version of the article, which is available at www.joem.org.
