[How to analyze and interpret the effective values in clinical trials].
The analysis of the effective value obtained in clinical trails should take account of both sides of its size and precision, for its interpretation, the general principles of: accuracy, explicitness and quantification should be complied. Criteria such as relative risk (RR), relative risk reducing rate (RRR), absolute risk reducing rate (ARR) and number needed to treat (NNT) an important clinical event, etc. are commonly used in the primary outcomes interpretation, while the methods to express the effective size and precision of surrogate outcomes and intermediary outcomes are needed to be further studied. Many problems for give expression to the outcome of TCM clinical trail still remain to be solved.
