^aP < 0.05. This suggests that the observed correlation is statistically significant at the 5% level, meaning there is less than a 5% chance of observing such results if the null hypothesis were true.

^bP < 0.01, indicating a higher level of statistical significance. This implies that the observed correlation is statistically significant at the 1% level, with less than a 1% chance of occurring under the null hypothesis.

Pearson’s correlation test was used to analyze the correlation. The P value provides a quantitative measure of the statistical significance of the observed results.
