* indicates the coefficients are statistically significant at P < 0.05. Pair with positive correlation coefficients and P < 0.05 tend to increase together. For the pairs with negative correlation coefficients and P < 0.05, one variable tends to decrease while the other increases. For pairs with P > 0.05, there is no significant relationship between the two variables
