3. Fig 2
BDNF plasma levels (in picograms per milliliter) in healthy subjects, as measured by means of ELISA and stratified according to rs6265 genotype. A Kruskal-Wallis test was initially used to test whether the different genotypes were associated with altered BDNF protein levels in plasma. Pairwise Mann-Whitney tests were then carried out to determine whether there were significant differences in BDNF levels between genotypes. ∗P < .05.

Total IgE levels in sera from healthy subjects, as measured by using ImmunoCAP and stratified according to rs6265 genotype. The Kruskal-Wallis test was initially used to test whether the different genotypes were associated with altered plasma IgE levels. The pairwise Mann-Whitney test were then carried out to determine whether there were significant differences in IgE levels between genotypes. ∗P < .05.
