| Pearson correlation coefficient (r =)** | |||||||||
*p value ≤ 0.05 was considered statistically significant.
**Based on Pearson-correlation coefficient (r), the association between the phenotypic and genotypic variables was determined as: |r|< 0.3; weak correlation, 0.3 <|r|< 0.5; moderate correlation, 0.5 <|r|< 0.85; strong correlation.
