[Progress in research of pragmatic-explanatory continuum indicator summary].
Randomized controlled trial (RCT) can be designed as explanatory trial and pragmatic/practical trial (PCT) for clinical effect evaluation. The pragmatic/practical trial reflects the intervention effect under actual clinical condition, which has relatively good extrapolation, but its internal validity is relatively poor. ⋯ Many RCTs have the properties of the two designs at the same time, Pragmatic-explanatory continuum indicator summary (PRECIS) can be used in the design of RCT for the balance between internal validity and external validity. There are few available reports about the application of PRECIS in China at present, so this paper summarizes the basic principles, characteristics of PRECIS and the application of PRECIS in order to provide reference for the clinical trial design in China.

Meta Analysis[Meta-analysis on the efficacy and adverse events of aspirin plus clopidogrel versus aspirin-monotherapy in patients with ischemic stroke or transient ischemic attack].
To present the systematic assessment on the efficacy and bleeding adverse events of dual-antiplatelet therapy with aspirin and clopidogrel versus aspirin-mono-antiplatelet therapy in patients with ischemic stroke or transient ischemic attack. ⋯ The combined therapy of aspirin and clopidogrel could reduce the risk of recurrence of ischemic stroke and TIA patients, but increase the risk of bleeding, when compared to the group that using aspirin alone for the therapy. In Chinese population, the combined therapy seemed more effective than using aspirin alone in reducing the recurrence of stroke, but without increasing the risk of bleeding.
