Scientific journals are important scholarly forums for sharing research findings.
Editors have important roles in safeguarding standards of scientific publication
and should be familiar with correct presentation of results, among other core
competencies. Editors do not have access to the raw data and should thus rely on
clues in the submitted manuscripts. To identify probable errors, they should look
for inconsistencies in presented results. Common statistical problems that can be
picked up by a knowledgeable manuscript editor are discussed in this article.
Manuscripts should contain a detailed section on statistical analyses of the
data. Numbers should be reported with appropriate precisions. Standard error of
the mean (SEM) should not be reported as an index of data dispersion. Mean
(standard deviation [SD]) and median (interquartile range [IQR]) should be used
for description of normally and non-normally distributed data, respectively. If
possible, it is better to report 95% confidence interval (CI) for statistics, at
least for main outcome variables. And, P values should be presented, and
interpreted with caution, if there is a hypothesis. To advance knowledge and
skills of their members, associations of journal editors are better to develop
training courses on basic statistics and research methodology for non-experts.
This would in turn improve research reporting and safeguard the body of
scientific evidence.
