Multivariate logistic regression of factors that may affect diastolic dysfunction revealed that there was no statistically significant in stages of CKD (p value = 0.07), serum Ca (p value = 0.82), and serum 25(OH) cholecalciferol (p value = 0.59) while there was statistical significance in serum phosphorus (p value = 0.03), serum PTH (p value = 0.002), and hypertension (p value = 0.03) (Table 8). Here, PTH is linked to hypertensive disorder.
