title: [Utilization++ of statistical analysis in original articles published in the Revista Clínica Española (1992-1993)].
abstract: OBJECTIVE
  To report the types of statistical analysis performed and to quantitate statistical accessibility in the originals of Revista Clínica Española from 1992 to 1992.
  
  
  METHODS
  Ninety-one originals were reviewed. Statistical analysis were classified according to 18 categories and statistical accessibility was evaluated from the same categorization.
  
  
  RESULTS
  Seventy-four percent of originals used inferential methods. The most frequently used categories were Bivariable tables (46%) and t and z test (42%). Thirty-six percent of originals used some multivariable analysis and particularly the Analysis of survival (12%).
  
  
  CONCLUSIONS
  Considering the high frequency of use of multivariable techniques, investigators need to have some knowledge on statistics beyond a basic course.
