When the above article was first published online, the bottom row of data, relating to MAN activity, in Table 4 was missing. This has now been corrected in both the print and online versions as follows:

Table 4. Sensitivity, specificity and cut-off values for salivary activity of α-fucosidase (FUC), β-galactosidase (GAL), β-glucuronidase (GLU), β-hexosaminidase A isoenzyme (HEX A) and α-mannosidase (MAN), in alcohol-dependent non-smokers (ANS) and alcohol-dependent smokers (AS) at 1st day and at 50th day of the abstinence (post chronic drinking period).

^a Cut-off values for salivary FUC, GAL, GLU, HEX A and MAN activities (pKat/ml) were obtained for alcoholic individuals by ROC analysis.
