Compare detailed information for two concepts using the SCT Browser's Comparing Perspective.

Prerequisite steps: Browse SNOMED CT International Edition concepts


StepsReferences

From any view in the SCT Browser, press  on the Perspective button in the header bar to see a drop-down options list of available perspectives:

  • Full 
  • Comparing 
  • Comparing hierarchy 
  • Responsive (tablets, phones) 

Select Comparing to switch the presentation.

Perspective: Comparing maintains the browser header bar, but changes to show two side-by-side Concept Details panels, with a full-width Search panel below them.

The Search panel is simply an expanded full-width version of the Search panel in Perspective: Full, with identical features and behaviour, for the purpose of populating the two Concept Details panels.

Reloading clears Perspective: Comparing

Reloading the page will reset the SCT Browser to the Perspective: Full default presentation.

In the Search panel, find the first concept to be compared (as described in Find the SCTID for a known concept term or Find the FSN or PT for a known concept SCTID).

In the Search Results list, press and hold the result row for the first concept to be compared. The selected row will be highlighted in blue, and a "Drag this" tooltip will appear.

Whilst holding the cursor selection, drag the selected item onto the concept Summary FSN label in the blue details box in the left-hand Concept Details panel Summary tab. Whilst dragging, the concept FSN term will appear alongside the cursor arrow.

When the cursor is over the Summary FSN label "drop-zone" a drop-target symbol will appear. Release the cursor hold to "drop" the concept.

Following a search result link also sets the first comparison focus

The left-hand Concept Details can also be populated by simply clicking on a search result.

The left-hand panel will now show the Concept Details Summary  tab for the dropped concept, and all the other context tabs can be navigated within the left-hand panel whilst maintaining the dropped concept focus.

Now use the Search panel again to find the desired comparison concept, and repeat the same steps to select, drag and drop, but this time drag the comparison concept to the Summary box of the right-hand Concept Details panel.

Following a search result link will not set the second comparison focus concept

The right-hand Concept Details can only be populated by drag and drop from the results list. Clicking on a search result will only populate the left-hand Concept Details panel, which could lose focus on a comparison concept already placed there.

Drag and drop works from any selected concept link in view

As well as using search results entries, each Concept Details can also be populated by drag and drop from the FSN label link in the other Concept Details, to show the same concept in each. This is an alternative way to set up side-by-side comparison of historical versions if already in Perspective: Comparing.

The two Concept Details context tabs can now be compared side-by-side.

Panel sizes can be adjusted

The relative sizes of the three panels can be adjusted by pressing and dragging their grey border bars. This can be useful to minimise the Search panel height once concepts are loaded for comparison, as shown in the adjacent screenshot.

The two Concept Details context tabs can be navigated independently whilst retaining their focus concept for side-by-side comparisons of the information in each context tab.

Once done with comparisons, select Full in the header bar Perspective button drop-down options list to switch back to Perspective: Full.
