title: [A SAS marco program for batch processing of univariate Cox regression analysis for great database].
abstract: OBJECTIVE
  To realize batch processing of univariate Cox regression analysis for great database by SAS marco program.
  
  
  METHODS
  We wrote a SAS macro program, which can filter, integrate, and export P values to Excel by SAS9.2. The program was used for screening survival correlated RNA molecules of ovarian cancer.
  
  
  RESULTS
  A SAS marco program could finish the batch processing of univariate Cox regression analysis, the selection and export of the results.
  
  
  CONCLUSIONS
  The SAS macro program has potential applications in reducing the workload of statistical analysis and providing a basis for batch processing of univariate Cox regression analysis.
