[Specification of statistical graphics in medical research].

Statistical graphics has a long history and is an important mean to present study design, analysis results and conclusions of medical research. A survey of statistical graphs of recent publications in Chinese and English academic journals shows that scientific and technical specifications of statistical graphics are still lacking. Based on the requirements of statistical graphics in prestigious medical journals (NEJM, Lancet, JAMA and The BMJ), this paper summarizes the technical requirements, key points of design of statistical graphs and practical conditions of common statistical graphs to provide reference for clinical researchers.统计图形历史悠久，是呈现医学研究设计、结果、结论的重要方式。纵观近年来中英文学术期刊中的统计图形可知，当前医学研究人员对统计图形的科学性和规范性的把握尚有不足。本文以NEJM、Lancet、JAMA、The BMJ四大权威医学期刊中统计图形的要求为切入点，总结出统计图形的技术要求、设计要点以及常见统计图形的实用条件、注意事项，以供医学研究者参考。.
