5. Click on the Graph tab in the Outcome Properties window. 5 点击―Outcome Properties‖对话框中的―Graph‖标签。
6. In the Scale field, enter ?1‘ and click Apply. Note that the scale of the forest plot has changed to -1 to 1. You can set the forest plot scale to any value, not only the values available using the slide control in the content pane.
6 在规模（Scale)中输入―1‖，点击应用（Apply）。注意森林图(forest plot)的数据范围变为-1～1。除了使用内容面板（content pane）滑动控制方式取值外，你可以使用这种方法将森林图(forest plot)的数据范围设定成任何值。
7. In the Left Graph Label box, enter ?Favours caffeine‘. 7 在―Left Graph Label‖中，输入―Favours caffeine‖。

9. Click Apply. Note that the forest plot labels have changed.
9 点击应用（Apply）。注意森林图(forest plot)中的标签（labels）变化。
Note: By default, RevMan assumes that outcomes are bad (e.g. headache). If you are measuring a good outcome (e.g. alertness), swap the graph labels so that the opposite side favours the treatment group.
注意：RevMan默认假设结局是有害的（比如，头痛）。但是，如果你测量的是有益结局（如警觉），交换图形标签（graph labels)，这样相反的一端倾向干预组（treatment group）。
10. Click the Analysis Details tab. 10 点击―Analysis Details‖标签。
11. Under Totals, select No Totals. Under Study Confidence Interval, select 99%. 11 在―Totals‖下，选择―No Totals‖。在―Study Confidence Interval‖，选择―99%‖。
12. Click Apply. Note that the lines representing the confidence interval for each study have become wider.
12 点击应用（Apply）。注意表示每个研究置信区间（confidence interval）的水平线变长了。
13. Check the Swap event and non-event option, and click Apply. RevMan will now display results for participants who did not have a headache. The forest plot will be reversed, including the labels at the bottom, and the summary estimate will change.
13 点击―Swap event and non-event‖选项，然后点击应用（Apply）。RevMan将显示没有头痛的参与者的结果。相应地，森林图(forest plot)互换了，包括底部的标签（labels），合并估计值（summary estimate）也会改变。
14. Click the Graph tab. 14 点击―Graph‖标签。
15. In the Sort By area, select Year of study and click Apply. Note the change in the forest plot.
15 在―Sort By‖区域，选择―Year of study‖后点击应用（Apply）。注意森林图(forest plot)的变化。
16. Select User defined order and click OK. There will be no change to the forest plot, but you can now re-order the studies in the outline pane.
16 选择―User defined order‖后点击―OK‖。森林图(forest plot)没有任何变化，但是现在你可以在大纲面板（outline pane）改变研究顺序。
17. In the outline pane, click the key icon next to the Headache outcome. 17 在大纲面板（outline pane），点击结局Headache下方的钥匙图标。
18. Select the Oohlahlazza study and click the Move Up button on the outline pane toolbar. Note the change in the data table and forest plot. 18 选中―Oohlahlazza‖研究，点击大纲面板（outline pane）上方工具栏的―Move Up‖按钮（译者注：在―Oohlahlazza‖研究上点击右键选择―Move Up‖也行。）
Adding subgroups
第四节 增加亚组
RevMan allows you to divide outcomes into subgroups. You can add the subgroups when you first create an outcome, or add subgroups to an existing outcome. RevMan允许你将结局分入亚组。你可以在创建结局时就添加亚组或者在一个已创建的结局后添加亚组。
1. In the outline pane, right-click the Headache outcome and select Introduce Subgroup. A subgroup will appear in the outline pane with the default name ?New subgroup‘. All the included studies will be listed under the new subgroup.
1 在大纲面板（outline pane），右键点击结局Headache，选择―Introduce Subgroup‖。在大纲面板（outline pane）里就会出现一个命名为―New subgroup‖的亚组。所有纳入的研究都包含在这个亚组内。
2. In the outline pane, select the New Subgroup, then right-click and select Rename Subgroup.
2 在大纲面板（outline pane），选中―New Subgroup‖，右键点击选择― Rename Subgroup‖。
3. Enter the name ?One caffeine dose‘. Click elsewhere to close the editing box. 3 输入新名称―One caffeine dose‖。随意点击其他地方退出编辑。
4. In the outline pane, select the Headache outcome and click the Add Subgroup button on the outline pane toolbar. This will open the New Subgroup Wizard. 4 在大纲面板（outline pane），选择结局Headache，然后点击大纲面板工具栏（outline pane toolbar）上的―Add Subgroup‖按钮。一个― New Subgroup Wizard‖对话框弹出。
5. Enter the Name ?Two caffeine doses‘ for the new subgroup and click Next. 5 输入新亚组的名称―Two caffeine doses‖，点击下一步（Next）。
6. For your next action, select Edit the new subgroup and click Finish. Note that there is now a separate section in the data table for each subgroup.
6 接下来，选择―Edit the new subgroup‖，然后点击完成（Finish）。注意数据表中每个亚组是处于不同部分的。
7. In outline pane, click the key icon to see the studies listed under the One caffeine dose subgroup.
7 在大纲面板（outline pane），点击钥匙图标，查看位于―One caffeine dose‖下的研究。
8. Select the Oohlahlazza study and click the Cut button on the toolbar. 8 选中―Oohlahlazza‖研究，点击工具栏上的―Cut‖按钮。
9. Select the Two caffeine doses subgroup and click the Paste button. 9 选中―Two caffeine doses‖亚组，点击―Paste‖按钮。
10. Click the key icon to see that the Oohlahlazza study now appears under the Two caffeine doses subgroup. Note that the study has also moved in the data table in the content pane, and the forest plot shows separate results for each subgroup.
10 点击钥匙图标，查看―Oohlahlazza‖研究已经位于―Two caffeine doses‖亚组中了。注意在内容面板（content pane）中数据表中研究的移动，森林图（forest plot）也分开显示不同亚组的数据。
11. In the outline pane, select the Headache outcome and click the Properties button on the outline pane toolbar.
11 在大纲面板（outline pane），选择结局Headache，点击大纲面板工具栏（outline pane toolbar）上的―Properties‖按钮。
12. In the Analysis Details tab, under Totals, select Subtotals only and click OK. 12 在―Analysis Details‖标签里，在―Totals‖下选择―Subtotals only‖，然后点击―OK‖。
The forest plot now includes two black diamonds showing the summary effect for each subgroup. Subgroup summary statistics are included in the data table.
现在，森林图（forest plot）用两个黑色菱形表示每个亚组的合并效应（summary effect）。亚组的总结统计也显示在数据表中。
Copying an outcome or comparison
第五节 复制结局或对比
If you wish, you can avoid typing the information again by copying an existing outcome or comparison.
