Cells include r-value with 95% confidence-interval values in parentheses. *Denotes p < 0.05 and **Denotes p < 0.01. We used †† to denote correlations that were statistically significant but with confidence intervals close to including zero. Gray font denotes no meaningful correlation. Black and bold indicates a significant correlation.
