临床上用于比较两种或多种治疗结果的分析方法一般分为两类。一类是回顾性分析:方法是把若干年以前使用过的疗法与某种新疗法之间进行分析比较;另一类是前瞻性(又称预期法)分析:方法是在事先经过科研设计并按设计观察有关指标,然后对资料进行整理分析。据一般医学期刊统计,临床分析稿件的刊出率约在1/2以上。可见临床研究在科研中占有重要地位。但在文章中也发现一些问题,现提出来谈些粗浅看法。
Clinical analysis methods used to compare the results of two or more treatments generally fall into two categories. One type is a retrospective analysis: the method is to analyze and compare the therapy used in a few years with a new therapy; the other is a prospective (also known as anticipation) analysis: the method is designed in advance and Observe the relevant indicators according to design, and then sort and analyze the data. According to the statistics of general medical journals, the publication rate of clinical analysis manuscripts is about 1/2 or more. It can be seen that clinical research plays an important role in scientific research. However, some problems have also been found in the articles. We now propose to talk about some superficial views.
