active comparators

In the final analysis 10 studies, comprising a total of 811 patients, were included. In these studies vitamin D was compared to placebo or active comparators [12]. However, the studies were very heterogeneous regarding doses used, included patients and co-interventions. The authors of the Cochrane review concluded that there was no consistent pattern that vitamin D supplementation was associated with greater efficacy than placebo.

积极的比较试验？

最终分析纳入了10项研究，共811名患者。在这些研究中，维生素D与安慰剂或积极的比较试验进行了比较[12]。然而，关于使用的剂量，这些研究非常不同，还包括患者和联合干预也不一致。Cochrane综述的作者得出结论，没有一致的模式表明补充维生素D与比安慰剂更有效。
