title: [Type two error and its relevance for interpretation of results. Quality audit of the Journal "Strahlentherapie und Onkologie].
abstract: BACKGROUND
  The statistical quality of the contributions to "Strahlentherapie und Onkologie" is assessed, aiming for improvement of the journal and consequently its impact factor.
  
  
  METHODS
  All 181 articles published during 1998 and 1999 in the categories "review", "original contribution", and "short communication" were analyzed concerning the appropriate consideration of Type II error.
  
  
  RESULTS
  Ninety-nine publications were excluded from analysis for different specified reasons. In none of the remaining 82 clinical publications Type II error was considered.
  
  
  CONCLUSIONS
  Authors, peer reviewers, and editors could contribute to improve the quality of the journal by setting value on adequate consideration of Type II error.
