ABSTRACT
BACKGROUND:
Statistical errors have been noted in a large percentage of articles appearing in medical journals. Their incidence in the Annals of Dermatology and the Korean Journal of Dermatology, however, has not been studied.OBJECTIVE:
The purpose of this study was to evaluate the accuracy of statistical methods in the Annals of Dermatology and the Korean Journal of Dermatology.METHOD:
Original papers using the t test in the Annals of Dermatology(AD) and in the Korean Journal of Dermatology(KJD) from January 1990 to July 1994 were analyzed for correctness of statistical methods.RESULTS:
Of the 376 original papers in the period considered, 78(20.7%) presented t tests and 43(55.1%) of these also contained some errors. Of the 9 papers from the Annals of Dermatology, 4(44.4%) included at least one error. Of the 69 papers from the Korean Journal of Dermatology, 39(56.5%) included at least one error.CONCLUSION:
Misuse of statistical methodology may not be uncommon in the two Korean Dermatology journals, and it would be prudent to give more attention to statistical methodology.
