Cumulative map graphs provide a way to compare strength of associations between a selected drug and events across multiple subsets, which are typically based on a continuous variable such as year. See Using a subset variable for more information.
The map graph on the Drugs tab shows data for all subsets included in the data mining run.
For information about statistics in the graph, see MGPS computations.
1. To set options for the graph, click Options.
2. Specify the following options and click OK. The options apply to the specific chart, and are saved as part of the layout.
Option |
Description |
||||||||||||||||||||||||||||
N at least |
Display only combinations with an observed count (N) of at least the specified number. |
||||||||||||||||||||||||||||
EBGM at least |
Display only combinations with an EBGM score of at least the specified number. |
||||||||||||||||||||||||||||
EB05 at least |
Display only combinations with an EB05 value of at least the specified number. |
||||||||||||||||||||||||||||
At most ____ associations |
Display no more than the specified number of combinations. You can display up to 200 combinations. If combinations are excluded because of this limit, a message appears below the graph. |
||||||||||||||||||||||||||||
Show value of |
In each cell of the grid, display the numeric value of N (observed), EBGM, or EB05. You can also select Leave blank to display a grid without labels. Cells with no occurrences are empty. |
||||||||||||||||||||||||||||
Color by |
Indicate whether the cell color should be controlled by:

||||||||||||||||||||||||||||
Order by first occurrence of |
Indicates how to order drug-event combinations in the graph, based on descending order of N, EBGM, or EB05 values. This ordering is applied to combinations for the first subset. If the maximum number of combinations is not reached, the ordering is applied to combinations for the second subset, and so on until the maximum number of combinations is reached. (The maximum number of combinations is determined by the At most __ associations option.) For example, suppose that the graph shows values of EBGM and has at most six combinations. You order by the first occurrence of EBGM > 2. Combinations are ordered in descending order of EBGM as follows:

3. You can point to a cell of the graph to display statistics for the combination represented by the cell. Long drug or event terms may end in an ellipsis in the label on the graph itself. In these cases, you can point to the cell to see the full terms.
4. If you click on a cell of the graph, you can then drill down to a list of cases for the cell.
