统计学意义与临床意义距离有多远?——医学文献中统计分析结果解读需仔细

Significant difference, statistically or clinically——Pay more attention to the statistical analysis in medical references

临床医学科研离不开统计学。只有了解该研究资料的特点,所选择变量的性质,注意%和95%可信限的关联和统计学意义与临床意义的差别,强调机制评估的重要性,才能对统计分析结果的临床意义作恰如其分的解释。

We can not do any clinical research if knowing nothing of statistics. In order to understand the results from a clinical research, readers must know the characteristics of the data, the features of the selected variables, the relation between % and 95% confidence interval, as well as the definitions of difference in clinical and statistical analysis, and it may be more important to make the evaluation of mechanism based on suitable explanation of clinical significance by means of statistical results.
