Abstract

Over the years, the use of statistics to evaluate experimental data in ophthalmology has increased. The present study sought to assess the frequency and types of statistical techniques used in ophthalmic journals. We reviewed 974 original articles from the Archives for 1970, 1980, and 1990; the American Journal of Ophthalmology for 1990; and Ophthalmology for 1990. Of the 592 articles reviewed for 1990, 391 (66.0%) contained statistics, with measures of central tendency most commonly used (385 articles [65.0%]), followed by dispersion (298 [50.3%]), t test (120 [20.3%]), and contingency tables (98 [16.6%]). A reader familiar with 10 statistical techniques would have "statistical accessibility" to 526 (88.9%) of 1990 articles. A statistically significant difference was found in the percentage of articles containing statistical methods among the journals (P = .0003; Archives, 75.3%; Ophthalmology, 66.8%; and American Journal of Ophthalmology, 55.2%).

摘要

多年来，在眼科领域运用统计学来评估实验数据的情况日益增多。本研究旨在评估眼科期刊中所使用的统计技术的频率和类型。我们查阅了《档案》1970年、1980年和1990年的974篇原创文章，以及《美国眼科杂志》1990年和《眼科学》1990年的文章。在查阅的1990年的592篇文章中，391篇（66.0%）包含统计学内容，其中最常用的是集中趋势测量（385篇文章[65.0%]），其次是离散度（298篇[50.3%]）、t检验（120篇[20.3%]）和列联表（98篇[16.6%]）。熟悉10种统计技术的读者能够“统计性地理解”1990年526篇（88.9%）的文章。在各期刊中，含有统计方法的文章所占百分比存在统计学显著差异（P = .0003；《档案》，75.3%；《眼科学》，66.8%；《美国眼科杂志》，55.2%）。
