Despite the fact that proteinuria improvement and renal function protection usually do not take place in parallel soon after vitamin D therapy in our evaluation, series of research [382] have invariably inferred that albuminuria reduction is essential for future renal outcomes. The improvement of hypercalcemia is actually a prospective hazard related to vitamin D therapy. Though negative final results were reported in particular RCTs, the pooled outcomes indicated an improved probability of hypercalcemia immediately after vitamin D therapy. This result is constant with other metaanalyses that evaluated individuals at all CKD stages [43], and these findings indicate that serum calcium concentrations need to be clinically monitored when CKD patients are taking vitamin D supplements. In this evaluation, we obtained no evidence of superiority for either the newer vitamin D compounds or the established compounds when it comes to their effect on proteinuria, renal function, hypercalcemia or other events. To the ideal of our information, this can be the first metaanalysis to evaluate randomized trials exploring the effects of vitamin D compounds on renal function in nondialysisdependent CKD individuals. However, our evaluation and, in some circumstances, the supplies contributing to our analysis have limitations. A lot of the trials evaluated were shortterm, frequently lasting no extra than two years, which implies that clinical outcomes, for instance allcause death plus the occurrence of cardiovascular events, might not reflect the intrinsic impact of vitamin D therapy. In addition, randomized clinical trials investigating the effects of vitamin D on proteinuria have been limited in number, and publication bias, though ina.
