Correction

Unfortunately, after publication of this article [1], it was noticed that some corrections to Table 2 were not carried out. The corrected Table 2 can be seen below and the original article has also been updated to reflect this.

Lymphocytes and monocytes are given as percentage of total white cell count. Differences between tertiles were analyzed using the independent samples t test when normally distributed or the Mann-Whitney U test when not normally distributed. P values < 0.05 were considered significant. Values are presented as mean ± SD or medians and 25th–75th percentile
