【摘要】 目的探讨医学研究中出现的一类问题,即高危人群检出指标的计算、报告及组间比较的统计学检验的正确性。方法查阅文献,列举当前研究者对高危人群检出指标的计算方式及组间统计学检验方法。结果当前文献报告的高危人群检出率与组间的统计学检验方法是错误的;而对组间进行的统计学检验并非是对高危人群检出率间进行的检验。结论建议对高危人群检出指标应计算及报告高危人群检出率;而对组间比较时,应去除病人人群,检验高危人群的构成比间是否有统计学差异,并在文中加以说明。更多还原

【Abstract】 Objective To evaluate the calculation and report of detection index and the statistics analysis of group comparison in high risk group,a problem of medical science study.Methods Relevant literature was consulted so that the methods could be listed of the detection index and the current statistic analysis of group comparison in high risk group.Results The current report about detection ratio and the statistics analysis of group comparison in high risk group proved to be mistaken,and the statistics analysis of group comparison was not the comparison of detection ratios in high risk group.Conclusions It is necessary to calculate and report the detection ratio when expressing the detection index.The statistics difference should be tested about constituent ratio in the group comparison,after excluding patient group.At the same time,some explanation should be given by the author in the composition.更多还原
