The model adopts continuity equation, diffuse wave model, and the Mannings equation for surface runoff routing, while uses the Green and Ampt infiltration theory and Darcys Law for subsurface runoff treatment. Uncertainty analysis incorporating Monte Carlo simulation and a Maximum Likelihood Estimation and Efficiency Coefficient is used to retrieve optimal parameter values and to estimate the confidence interval for the simulation results.

Most research have focused on how to find the confidence interval for CER, NHB, ICER, INHB.

更多的文献专注在如何找成本效益比、总健康效益、增加成本效益比、增加总健康效益的信赖区间。

After adjustment for body mass index and other potential confounders, the relative risks of total mortality were 1, 1.28 (95% confidence interval , 1.04-1.58), 1.40 (95% CI, 1.14-1.72), 1.54 (95% CI, 1.26-1.88), and 1.95 (95% CI, 1.60-2.38) across the lowest to the highest waist-hip ratio quintiles.

在调整体重指数和潜在的混杂因素后，全部死亡率的相对危险在参照组为1，在从最低到最高的腰臀比值五等分后的的组中分别为：1.28 (95%可信区间， 1.04-1.58)， 1.40 (95%可信区间， 1.14-1.72)， 1.54 (95%可信区间， 1.26-1.88)，和 1.95 (95%可信区间，1.60-2.38)。

For urine specimens obtained at 21 to 32 weeks, the adjusted odds ratio for the risk of preeclampsia to begin before 37 weeks of gestation was 22.5 (95% confidence interval, 7.4-67.8) for the lowest quartile of control PlGF concentrations (18 pg/mL), compared with all other quartiles.

这项研究的限制因素，包括样本几乎是在10年前获取的；每一位女性的尿液样本只取样三次；缺乏子癫前症的类似症状资料。

Compared with the single-bounded questionnaire format, the double-bounded questionnaire format could obtain more information about the respondents' willingness to pay, hence, it reduces the confidence interval range and improves the estimation accuracy of the greatest willingness to pay. At the pilot practice for three continuous years, the percent of banana windstorm insurance pilot size in the total banana planting area was less than 10% in Hainan. Combined with this research result, the author holds that Hainan finance should strength the subsidy to banana windstorm insurance on the basis of 30% subsidy in two continuous years of 2007 and 2008, and the subsidy percentage should try to achieve 40%. At the same time, the premium rate should not be too low, 18% is suitable.

与单边界问卷格式相比，双边界问卷格式能够获得被调查者支付意愿的更多信息，从而缩小了估计的置信区间，提高了最大支付意愿的估计精度；在连续3年的试点实践中，海南香蕉风灾保险试点规模占其香蕉种植面积不足10%，结合本研究结果，笔者认为海南省财政应在2007、2008连续两年30%的财政补贴基础上进一步加大对香蕉风灾保险业的补贴力度，力争补贴比例达到40%左右，同时费率也不宜过低，宜保持在18%左右。

If the horizontal line represents the 95% confidence interval of the indexes including odds ratio, relative risk, weighted mean difference, and standard mean difference crosses the vertical line, the effect of test group is not signficant with that of control group; if the horizontal line lies to the right of the vertical line, it indicates that the test group is significantly effctive.

它在平面直角坐标系中，以一条垂直的无效线(横坐标刻度为 1或 0 )为中心，用平行于横轴的多条线段描述了每个被纳入研究的效应量和可信区间(confidenceinterval，CI)，用一个棱形描述了多个研究合并的效应量及可信区间。

In this paper , the statistic significance and clinical application of forest plots in a meta-analysis have been fully discussed. If the horizontal line represents the 95% confidence interval of the indexes including odds ratio, relative risk, weighted mean difference, and standard mean difference crosses the vertical line, the effect of test group is not signficant with that of control group; if the horizontal line lies to the right of the vertical line, it indicates that the test group is significantly effctive. If the horizontal line lies to the left of the vertical line, it indicates that the control group is more effective.

对Meta-分析的森林图的统计学意义和临床应用做了较为详细的解释：当统计指标比值比、相对危险度、加权均数差和标准化均数差的95%可信区间横线与森林图的无效线(横坐标刻度为1或0)相交时，试验组的效应量等于对照组，试验因素无效；当其95%可信区间横线不与森林图的无效线相交且落在无效线右侧时，试验组的效应量大于对照组；当其95%可信区间横线不与森林图的无效线相交且落在无效线左侧时，试验组的效应量小于对照组。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
