The correlation coefficient rr measures the strength and direction of the linear relationship between two variables. It ranges from -1 to 1: r=1: Perfect positive correlation r=−1: Perfect negative correlation r=0: No correlation Values closer to 1 or -1 indicate a stronger relationship, wh...

In the subgroup comparison, FMD showed a strong negative relationship with preZmax in the CA, CAA and SCA groups, and the absolute value of the correlation coefficient was larger in the CA group than any of the KD, CAA, NA and NCA groups. However, such a relationship was not detected ...
Pearson's r is better known as thecorrelation coefficient. It quantifies the strength of the correlation between two variables, as well as the direction of the relationship. R always falls between -1 and 1, with 0 representing no evidence of correlation. A perfectly linear negative relationship...
