Abstract

Over the years, the use of statistics to evaluate experimental data in ophthalmology has increased. The purpose of this study is to assess the frequency and types of statistical techniques, especially multivariate analysis used in ophthalmic jouranal. Seventy three of 202 articles from the Journal of the Korean Ophthalmological Society published in 1993 contained inference statistics. While only nine among 73 articles(12.3%) contained multivariate analysis in the Journal of the Korean Ophthalmological Society, 47 among 123 articles(38.2%) in Ophthalmololgy. This difference in frequency was statistically significant(Chi-square, p=0.003). The author suggest that ophthalmologists should learn more about statistical technique for better understanding of current articles and for production of refined data analysis.
