Models were adjusted for traditional CVD risk factors. Among all negative risk markers, coronary artery calcium score of 0 was the strongest, with an adjusted mean DLR of 0.41 (SD, 0.12) for all coronary heart disease and 0.54 (SD, 0.12) for CVD, followed by carotid intima-media thickness &lt;25th percentile (DLR, 0.65 [SD, 0.04] and 0.75 [SD, 0.04], respectively). High-sensitivity C-reactive protein &lt;2 mg\/L and normal ankle-brachial index had DLRs &gt;0.80. Among clinical features, absence of any family history of coronary heart disease was the strongest (DLRs, 0.76 [SD, 0.07] and 0.81 [SD, 0.06], respectively). Net reclassification improvement analyses yielded similar findings, with coronary artery calcium score of 0 resulting in the largest, most accurate downward risk reclassification.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions\u2014<\/jats:title>\n                    <jats:p>Negative results of atherosclerosis-imaging tests, particularly coronary artery calcium score of 0, resulted in the greatest downward shift in estimated CVD risk.
