Lipid Profile changes made based on user response examples.

Study ID	Prototype Version	User issues identified	Average SUS score for each version	Changes that were implemented
3002	3	– Didn’t realize test components were clickable – Didn’t understand ranges well	65	– Addressed clickability by making components more obviously clickable (i.e.; added highlighted circle around result to encourage clicking, and “hover over” cues, Dotted lines placed around Result box totals) – Caution range added for HDL result
3003	4	– Clicked on “walk me through these results” to learn more about triglycerides, but didn’t click on view detailed results at the end of test description – not apparent it will lead somewhere else other than main result page – Didn’t know to click on test components to learn more about the component	95	– Link walk through to detailed results, not test description – Make components more clickable
3004	5	– Didn’t see a way to “go back” from test explanation	92.5	– Created a “back arrow” button that returns to the main display page
3006	6	– Confused about HDL having low range in red – initially thought “oh HDL is low, that’s good” which is incorrect because it’s supposed to be on the higher range. Trend in other ranges is that high is bad except with HDL	85	– Add additional low and/or high to equalize all ranges on the display
3011	7	– Labels inside of ranges are on the lower end of readability	96.3	– Increase size of label font and range boxes – use heavier font
