Table 1.
Demographic data of subjects.
Figure 1.
Scatter plot of proBDNF and mature BDNF serum levels in patients with MDD and healthy controls.
(A): Serum levels of proBDNF in 20 patients with MDD and 29 healthy subjects were below the minimum detectable concentration (0.5 ng/mL) of the proBDNF ELISA kits. Serum levels of proBDNF in patients with MDD did not differ from those of normal controls. (B): In contrast, serum levels (21.09±5.60 ng/mL) of mature BDNF in patients with MDD, were significantly lower than those (23.11±5.90 ng/mL) of normal controls.

Scatter plot of MMP-9 serum levels in patients with MDD and healthy controls.
Serum levels of MMP-9 in patients with MDD did not differ from those of normal controls.
Figure 3.
Relationships between MMP-9 serum levels and clinical variables in patients with MDD.
(A): There was a significant negative correlation (ρ = −0.366, p = 0.002) between MMP-9 serum levels and WHOQOL-BREF scores. (B): There was a significant negative correlation (ρ = −0.355, p = 0.003) between MMP-9 serum levels and SASS scores. (C): There was a significant positive correlation (ρ = 0.397, p = 0.001) between MMP-9 serum levels and the SIGH-D score.
Figure 4.
Relationships between clinical variables in patients with MDD.
(A): There was a significant negative correlation (r = −0.705, p<0.001) between the SIGH-D score and WHOQOL-BREF score in patients. (B): There was a significant negative correlation (r = −0.579, p<0.001) between the SIGH-D and SASS scores in patients. (C): There was a positive correlation (r = 0.404, p = 0.001) between the CogState composite score and QOL score in patients. (D): There was a positive correlation (r = 0.371, p = 0.002) between the CogState composite score and SASS score in patients.
