Abstract:

Every research article in thirteen chiropractic research journals published from January 1999 through February 2000 was evaluated for quality of analysis and design. All of the journals reviewed have membership in the Chiropractic Research Journal Editors' Council, which is a forum for the editors to improve their publishing practices. Three biostatisticians critically assessed the articles using a two-page checklist developed from review criteria used in biomedical literature. Of the seventy-three total articles reviewed, 21% lacked description of the study design, 77% did not provide a sample size justification, 26% reported inappropriate descriptive statistics, 26% reported conclusions not supported by the results, and information was often replicated. Of the fifty-five articles with a primary objective of testing, ten did not report any inferential statistics and nineteen reported inappropriate inferential statistics. The resulting recommendation is that investigators submitting manuscripts to journals use available guidelines in preparing their research reports and that reviewers use those same guidelines in critiquing the manuscripts.
