View a sector map for a product

A sector map for signal management data is a visual presentation of data for a product across all System Organ Classes (SOCs).

  • Each System Organ Class (SOC) is represented by a large tile in the sector map.
  • Each SOC tile is divided into smaller tiles representing Preferred Terms (PTs).
  • The color, size, and ranking of tiles provide a big picture overview of the adverse event profile of a product.
  • Data represented in the sector map includes all available data up through the current time period and is for a particular signal set.

When you view a sector map for a product, PTs are ranked in descending order of values of the statistic (EBGM, EB05, Chi-statistic, or PRR) that you choose. A color key indicates relative ranking. You can also list the ranked PTs below the sector map.

  1. In the left navigation pane, click the Signal Review icon (Signal Review icon).
  2. (Optional) From the Products By drop-down list, select a product grouping, then select a card to filter the Products table.
  3. Click the product's Row Action Menu (Row Action menu icon) and select a View Sector Map option:

    Note:

    If you are working from a multisource signal configuration, options for each configuration included in the multisource signal configuration appear in the menu. You can identify the secondary configurations by the prefix that matches the secondary configuration label defined in the multisource signal configuration.
  4. To set display options for the sector map, click Options below the sector map.
  5. If you point to a PT tile, the MedDRA PT, HLT, HLGT, and SOC appear. The following information for the combination of the product and the term that the tile represents also appears:
    • N—Observed number of cases with term.
    • EBGM—Empirical Bayesian Geometric Mean. A more stable estimate than RR; the so-called shrinkage estimate. For more information, see MGPS computations.
    • EB05—A value such that there is approximately a 5% probability that the true Relative Ratio lies below it.
    • PRR—Proportional Reporting Ratio. For more information, see PRR computations.
    • Chi-statistic—Chi-statistic associated with PRR. (If EBGM < 1, the Chi-statistic is expressed as a negative number, indicating that the product-event combination is more rare than expected). The Chi-statistic is the signed square root of Chi-square.
  6. To zoom in on a particular SOC, click anywhere on the SOC tile and select Zoom from the menu.
  7. If you click a tile for which N is at least 1, a menu appears and you can drill down to cases that include the PT represented by the tile or view statistics for the tile.
  8. To save the graph as an attachment to a topic, click Save to Topic. (This option is available if the Links option is checked and the Topics feature has been set up.)
  9. To close the Sector Map window, click Cancel.
