Correction

In the article ”First Nations hepatitis C virus infections. Six-year retrospective study of on-reserve rates of newly reported infections in northwestern Ontario,”¹ which appeared in the November issue of Canadian Family Physician, an error was inadvertently included. The corrections appear below.

The 2011 rate per 100 000 (95% CI) of newly reported cases of hepatitis C virus infection should have been 135.5 (112.7 to 158.3) in Table 1. This change affects the initial slope of the rates presented in Figure 1 but does not affect the overall increasing trend. The upper limit of the 95% CI for the 2014 rate should be 327.3. The correct versions of Table 1 and Figure 1 are presented here. The authors apologize for the error and any confusion it might have caused.
