Objectives:
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.
