Recommendations concerning statistical analysis, etc.
The editorial board of the Japanese Journal of Generic Medicines

Samples
When study samples are drugs used for medical purposes, givethe name of the manufacturer and the lot numbers if possible. If
symbols such as “A,” “B,” etc. are used, provide the reason.
Statistics
For comparison between 2 or more groups, it is recommended
to prepare the paper taking the following matters concerning dataaggregation, statistical analysis, and discussion into consideration:1)	The parameter that shows the fluctuation of measured values
should basically not be given in standard error, but in standard
deviation. It is desirable to show the data distribution visuallysuch as by a Box plot.
2)	For comparison of the mean between groups,2-a)	Discuss the uniformity of the arrangement of backgroundfactors (items) other than the evaluation item between thegroups to be compared.

842-b)	Describe the authors’ opinion on how large a difference inthe value of the subject indicator has to be considered as ameaningful difference (clinically significant differences).
2-c)	Describe the justification for the selection of the number ofsubjects and the number of cases in the study.
2-d)	Use multiple comparison to compare 3 or more groups.
2-e)	The p value should not be shown as p<0.05 or p<0.01, etc;
the precise p value should be shown.
2-f)	For the discussion of results based on statistical tests andstatistical estimations, clinically significant differences, thenumber of data (number of subjects and number of cases),etc. should be considered in addition to the results such as
statistical significance tests. Note that the statistical conclusion is not directly connected to clinical “equivalence” or“nonequivalence.” It may help to include and utilize a confidence interval so that a hasty discussion can be avoided.
Please take the recommendations listed above into consideration.
