Figures & data

Table 1. Characteristics of participants.

Group	Mean age (years)	Sex	BMI (kg/m^2)	Dg.	CDI score
Children with depression (n = 15)	15 ± 0.41	F(12), M(3)	21 ± 0.98	DD (n = 6) MADD (n = 9)	29 ± 2.12
Healthy children (n = 15)	15 ± 0.51	F(11), M(4)	19 ± 1.04	–	–

Dg.: diagnosis (ICD10); DD: depressive disorder; MADD: mixed anxiety and depressive disorder; CDI: children’s depression inventory

Data are expressed as mean ± SEM.

Figure 1. Morning and midday activity of alpha-amylase in the group of youths with depression (n = 15) and the group of healthy youths (n = 15). Results are expressed as dot plots with each dot representing individual subject with mean ± SEM represented by horizontal lines. Statistical significance as revealed by repeated-measures GLM with subsequent Tukey pairwise comparisons: *p < .05, *p < .001.

Figure 2. Morning to midday alpha-amylase slopes in the group of youths with depression (n = 15) and the group of healthy youths (n = 15). Slopes calculated from the line’s equations in the slope-intercept form are expressed as the values of angular coefficients m. Results are expressed as mean ± SEM. Statistical significance as revealed by t-test for independent groups.
