Using the OPAS Dashboard
Note: Click on an item to see more details.
The OPAS Dashboard has help icons that provide additional information about all the dashboard's components. Hover your mouse over the icons to learn more about what a component does.
The OPAS Dashboards are optimized for use in recent versions of Mozilla Firefox and Google's Chrome browser. Other browsers, such as Internet Explorer, and older browsers may not render this application correctly.
When you select a range of years, a trend plot appears. When you choose the same starting and ending year, a bar plot appears.
The plots are created using a tool called Plotly. When you hover over a plot, a toolbar appears in the upper-right corner: . Feel free to try all the tools on this toolbar to work with your plot, or visit this Plotly guide to learn move.
The first camera icon in the toolbar allows you to download the plot as a png image format.
Hover over each point estimate in a trend plot, or bar in a bay plot, to get a pop-up displaying more detail about the estimate.
In addition to using the toolbar, you can double-click the plot to zoom in, or click and drag on a region of the plot to zoom to that region. Double-click again to zoom back out.
Click on a table column heading to sort by that column. Click on it again to sort in the opposite order.
Click on any of the file-format buttons to download a file of that format.
Click on the 'Column Visibility' button to change which columns are visible.
Type in the Search box in the upper right-hand cover to filter the table rows to your search term.
Click on a column heading and drag right or left to rearrange columns.
By default, estimates are created for all Ohio women with a live birth. You can also filter your results to refine your analysis:
This option allows you to compare results across values of a variable, such as comparing results for different types of insurance coverage.
Remember to click the button to compute revised estimates based on your selection.
Estimates in the OPAS Dashboard are computed using data from OPAS respondents. The survey design makes the data representative of residential Ohio women with a live birth. Estimates in the plot are of the estimated proportion (percentage) of residential Ohio women with a live birth, while the table presents both the estimated percentage and estimated count of residential Ohio women with a live birth.
The 'I'-shaped line at the top of each bar or dot represents the 90% Confidence Interval for the estimate shown. This US Census Bureau page discusses what Confidence Intervals are and how to interpret them.
Suppression of Unreliable Estimates
When the precision of the estimates is too low, typically because the sample size for the estimate is too small, results are either hidden from view or are replaced with N/A. For an estimate to be displayed, all of the following must be satisfied:
The Table View provides a set of columns including both the estimated proportion (expressed as a percentage) and estimated count of Ohio women with a live birth, as well as a measure of the associated certainty of the estimate (the confidence interval) for each. Table columns are as follows:
|Estimated Percentage||The survey-weighted estimated percentage of the selected population who have a particular value for the indicator.|
|XX% CI LB Percentage||The lower bound (LB) for the XX% confidence interval (CI) of the estimated percentage.|
|XX% CI UB Percentage||The upper bound (UB) for the XX% confidence interval (CI) of the estimated percentage.|
|Estimated Count||The survey-weighted estimated number of Ohio women who have a particular value for the indicator.|
|XX% CI LB Count||The lower bound (LB) for the XX% confidence interval (CI) of the estimated number of Ohio women.|
|XX% CI UB Count||The upper bound (UB) for the XX% confidence interval (CI) of the estimated number of Ohio women.|
All variables in the OPAS Dashboard are derived from the Ohio Pregnancy Assessment Survey Series. OPAS questionnaires are documented at the OPAS Project Site.
