[Scientific articles in Ugeskrift for Laeger during a 25-year period. Analysis and interpretation of research results].
During a period of 25 years from 1959 to 1984, no essential alteration in the employment of descriptive statistics was observed in the original articles in the Ugeskrift whereas analytical statistics was employed to an increasing extent. In all of these volumes, defective, incorrect or less suitable employment of statistics could be demonstrated. Common problems were: analyses of materials in which some patients participated once while others participated on several occasions; debatable analyses of data on ranking scales; employment of 2-group tests on several groups; insufficient analysis of cross-over trials; lack of confidence intervals, and circular reasoning.
