Statistical analysis
The data were evaluated using descriptive statistics (number, percentage
distribution, mean, median, standard deviation, min-max values, etc.),
the Kruskal Wallis test and the Spearman’s correlation test. p
<0.05 was considered statistically significant. r=–1 is a
perfect downhill (negative) linear relationship. r= +1 is a perfect
uphill (positive) linear relationship
