We tested whether presenting such results in visual displays (number lines) could improve understanding.<\/jats:p>\n               <jats:p>Materials and Methods: We presented 1620 adults recruited from a demographically diverse Internet panel with hypothetical results from several common laboratory tests, first showing near-normal results and then more extreme values. Participants viewed results in either table format (with a \u201cstandard range\u201d provided) or one of 3 number line formats: a simple 2-color format, a format with diagnostic categories such as \u201cborderline high\u201d indicated by colored blocks, and a gradient format that used color gradients to smoothly represent increasing risk as values deviated from standard ranges. We measured respondents\u2019 subjective sense of urgency about each test result, their behavioral intentions, and their perceptions of the display format.<\/jats:p>\n               <jats:p>Results: Visual displays reduced respondents\u2019 perceived urgency and desire to contact health care providers immediately for near-normal test results compared to tables but did not affect their perceptions of extreme values. In regression analyses controlling for respondent health literacy, numeracy, and graphical literacy, gradient line displays resulted in the greatest sensitivity to changes in test results.<\/jats:p>\n               <jats:p>Discussion: Unlike tables, which only tell patients whether test results are normal or not, visual displays can increase the meaningfulness of test results by clearly defining possible values and leveraging color cues and evaluative labels.<\/jats:p>\n               <jats:p>Conclusion: Patient-facing displays of laboratory test results should use visual displays rather than tables to increase people\u2019s sensitivity to variations in their
