All correlations in the table are controlled for age and gender. The collections of words and phrases results are present with a minimum significant level at p < .05. Risk = correlations with r > 0, protective = correlations with r < 0. r = Pearson’s correlation coefficient, the range of r values: [min r-value, max r-value]. 95% CI 95% confidence interval: [lower bound, upper bound]. ***p < .001, **p < .01. *p < .05. All p-values were corrected using the Benjamini–Hochberg False Discovery Rate correction. The font size of the word in each word cloud represents the correlation strength, the larger the size the stronger the correlation was.
