The following abbreviations were used in the study:
X gr. “i” the average ABG in group “i,”
where “i” stands for number of the analyzed group (1–10)
SD gr. “i” standard deviation in the average ABG in group “i,”
where “i” stands for number of the analyzed group (1–10)
Statistically significant changes of the average value of ABG are in red (p<0.05).
