In the version of the article originally published online, there was an error in Table 3 (page 312). The B coefficient for the variable “Anki” should be 5.89 × 10−4 rather than 5.89 × 10−3. The exponent is correctly reported in the body text (page 311).
The online version of the original article can be found at http://dx.doi.org/10.1007/s40037-015-0220-x.
