The results indicate that a strong positive and significant correlation exists between ECM and APF with correlation coefficient of 0.7542, and an associated p-value of 0.0125. More so, strong positive and significant correlation was found to exist between ECM and APR with correlation coefficient of 0.8547 and a p-value of 0.0024. Furthermore, the correlation between ECM and FAP was found to be significant, strong and also positive with correlation coefficient of 0.5624 and an associated p-value of 0.0425.
