^aAbsolute magnitude of the negative correlation values are represented
^bUsing Cohen’s definition [44]: r _s = .10 to .29 (small); r _s = .30 to .49 (medium); r _s = .50 to 1.0 (large)
^cUpper bound 95 % confidence interval suggests true value potentially lies above the range specified
^dLower bound 95 % confidence interval suggests true value potentially lies in the range specified
