Z-VAD-FMK Untruths You Have Been Advised About
However, in our study, the crude ORs for these parameters (CKD stage, presence of cardiovascular disease and anemia) were not found to be statistically significant (Table ?(Table6).6). In the study involving 1026 pre-dialysis CKD patients ZVADFMK conducted by Urena et al. [8], a decline in the measured glomerular filtration rate (GFR) was independently associated with vitamin D deficiency. However, this was not observed in this study as serum creatinine, CKD stage and estimated GFR were all not found to be associated with vitamin D status. A possible reason for the lack of association is the small sample size of this study. Thus, these parameters were not considered for both Mt30 and Mt16 models. Table 6. Odds ratio of vitamin D deficiency by covariates found to be important in other studies In recent years, genome-wide association studies that examined the influence of genetic variations on the vitamin D status have been prevalent [21�C23]. These studies included populations from North America, Canada and Europe and showed that variants in GC (gene encoding vitamin D binding protein), DHCR7 [responsible for removing pre-cholesterol from the vitamin D pathway thus reducing the availability of a substrate for 25(OH)D], CYP2R1 [responsible for hydroxylation of the vitamin D precursor to 25(OH)D], CYP24A1 [responsible for 24-hydroxylation, degradation and excretion of 25(OH)D] and CYP27B1 [responsible for conversion of 25(OH)D to the active 1,25(OH)2D] affect 25(OH)D concentrations. However, these genetic effects and their corresponding Ozagrel associations with the vitamin D status in the Asian Smad inhibitor population have not been investigated and thus warrant further research. Model performance Validation sets for Mt30 and Mt16 had AUCs of 0.697 and 0.687, respectively. These AUCs were comparable with that of the US study conducted by Bhan et al. [7] using similar threshold serum 25(OH)D levels and logistic regression algorithm. Limitations A potential limitation of our study is the relatively small sample size of 219 CKD patients. Due to the lack of complete clinical, laboratory and medications information for some patients, certain clinically relevant parameters had to be excluded from model development. For example, the clinical data of height and weight were missing for 25 patients. Under the laboratory data, not all patients had their serum levels of corrected calcium and i-PTH measured. Additionally, total cholesterol and urinary protein concentrations were not collected. Nonetheless, it would be possible to reconstruct the model with the inclusion of these parameters when more information becomes available in the future. Only eight (3.7%) patients had serum 25(OH)D levels
