1·For dichotomous outcomes, we calculated risk ratios (RRs) and 95% confidence intervals (CIs).
对于二分结果，我们计算风险比(RR)和95%置信区间(CI)。
2·For dichotomous outcomes we calculated a relative risk with its associated 95% confidence interval and a number needed to treat.
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。
3·The standardised mean difference and relative risk were used for continuous data and dichotomous data comparisons, respectively.
对连续性数据及二分法的数据各自以标准平均差及相对风险来比较。
4·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.
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。
5·Summary effect sizes for dichotomous and continuous outcomes were calculated using a random effects model and heterogeneity was assessed.
二分项资料与连续资料均使用随机效果模式来计算总结效果大小，且说异质性也被评估。
