对于二分的结果变项我们计算相对风险以及其95%信赖区间、益一需治数。
For dichotomous outcomes we calculated a relative risk with its associated 95% confidence interval and a number needed to treat.
对于连续性的结果变项使用标准化或加权的平均值差异来分析处理资料,而对二分的结果变项则使用胜算比与95%信赖区间来分析处理资料。
Standardised or weighted mean differences were used to pool data for continuous outcomes and odds ratios were used to pool data for dichotomous outcomes, together with 95% confidence intervals.
If you knew only the third derivative of the function, you can have something quadratic in t without changing the outcome.
