摘要 临床研究者在解读试验结果时往往只重视P值的大小,但P值存在一定的局限性。把握度计算是设计研究方案及解释研究结果的有效工具,而用可信区间来展示数据则会促进对于阴性结果的新的解释的产生。在报道临床研究统计结果时,不但要给出假设检验的具体P值,还应该给出有关总体参数的95%置信区间,以给读者一个信息完善、说理清晰透彻的统计分析结果。 It is a trend that clinical researchers overemphasize on hypothesis testing and the P value. However,P value has some limitations in the presentation of study results. Power is a tool for study design and results explanation,especially for negative results. Confidence interval contains more information for clinical results than P value. P value,power,and 95% confidence interval should be provided in the clinical reports to facilitate the interpretation of the results.
