Overall , this meta- analysis shows that in diabetic patients , taking vitamin D had significant effects on hs-CRP and MDA levels , and significantly increased NO , TAC and GSH levels
In this systematic review and meta- analysis of r and omized controlled trials ( RCTs ) , the effects of vitamin D supplementation on biomarkers of inflammation and oxidative stress in diabetic patients are summarized .
Biases in Randomized Trials: A Conversation Between Trialists and Epidemiologists.
Trialists and epidemiologists often employ different terminology to refer to biases in r and omized trials and observational studies , even though many biases have a similar structure in both types of study . We use causal diagrams to represent the structure of biases , as described by Cochrane for r and omized trials , and provide a translation to the usual epidemiologic terms of confounding , selection bias , and measurement bias . This structural approach clarifies that an explicit description of the inferential goal -the intention-to-treat effect or the per- protocol effect-is necessary to assess risk of bias in the estimates . Being aware of each other 's terminologies will enhance communication between trialists and epidemiologists when considering key concepts and methods for causal inference
