1.交代统计研究设计:在写论著时应交代统计研究设计的类型和主要做法。如:调查设计包括前瞻性、回顾性或横断面调查研究;实验设计包括自身配对设计、成组设计、析图设计、正交设计等;临床试验设计包括属于第几期临床试验,采用了何种盲法措施等;统计研究设计的主要做法应围绕随机、对照、重复、均衡4个基本原则概要说明。2.资料的表达与描述:近似服从正态分布的定量资料用x±s表达,呈偏态分布的定量资料用M(QR)表达。用统计表时,要合理安排纵横标目,并将数据的含义表达清楚;用统计图时,应注意统计图的类型与资料性质相匹配,并使数轴上刻度值的标法符
1. Confirmation of Statistical Research Design: When writing a treatise, the types and main practices of statistical research should be accounted for. Such as: survey design, including prospective, retrospective or cross-sectional investigation and study; experimental design including self-matching design, group design, analysis of the design, orthogonal design, etc .; clinical trial design, including belonging to the first few clinical trials, Kinds of blind measures, etc .; The main practice of statistical research and design should focus on four basic principles of random, control, repetition, and balance summary description. 2. Data expression and description: Quantitative data approximating normal distribution were expressed as x ± s, and skewed distribution of quantitative data was expressed by M (QR). When using statistical tables, it is necessary to arrange the vertical and horizontal headings in a reasonable way and express the meaning of the data clearly. When using statistical charts, note that the type of statistical chart matches the nature of the data,
