-  * **Random/Fixed Effects:**  Across all Quantitative Synthesis pages, estimates and percentages displayed by Default are actually Random Effects calculations. To toggle to Fixed Effects (that is, an estimate based on an assumption of [[https://www.statisticshowto.com/experimental-design/fixed-effects-random-mixed-omitted-variable-bias/|constancy or non-randomness]]), use the toggle in the upper right of the table.+  * **Random/Fixed Effects:**  Across all Quantitative Synthesis pages, estimates and percentages displayed by Default are actually Random Effects calculations.

 +=== Table vs. Visual layout === 
 + 
 +The summary is displayed in table format to select up to three data elements to view alongside one another. You may wish to view the same data in a visual layout instead. Toggling "Visual" in the top right displays visuals for each intervention (or group of interventions if minimized) mimicking what you might recognize as a forest plot. This visual is intended to provide an alternative quick summarization of the presented data in a way end users may better understand and only displays one chosen data element at a time. 
 + 
 +While the odds ratio axes and I^2 are not provided in this summary table, the data for interventions can be viewed in detail on the NMA page.

 In this page, select the X and Y axes to designate the Data Elements of interest. This will generate a chart that shows the distribution of studies based on their rate of each Data Element. Furthermore, hovering over any node in the Distribution page will show you the study the node represents, and clicking on it will open a study modal showing the abstract, data, tags, and search history of that study. In this page, select the X and Y axes to designate the Data Elements of interest.

 +==== Filtering Synthesis ====
 +
 +You can also apply broader filters to view specific sets of studies via the Settings button in the top right. Learn more about [[wiki:synthesis:filters|Synthesis Filters.]]
 +
 +==== 5. Share or Embed ====
 +
 +Similar to QLS, you can share any of the Quantitative Synthesis pages by clicking on the share icon in the top right. You have the choice of sharing via a link or downloading a QR code.
 +
 +{{ :undefined:qns_ambed.png?nolink |}}
 +
 +If your nest is public (see Settings to do so) you will also have the option to embed QLS into a webpage. Simply copy the HTML code and paste it into your site of choice.
 +
 +Note: unlike in QLS, in QNS, there is no option to download a spreadsheet of filtered studies from Synthesis. Only nest users can access this data in Study Inspector --> Download --> MA Extraction.
