SCT was associated with an ischemic stroke hazard ratio of 1.4 (1.0\u20132.0) and an incidence rate difference amounting to 1.9 (0.4\u20133.8) extra strokes per 1000 person-years.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions\u2014<\/jats:title>\n                    <jats:p>We observed an increased risk of ischemic stroke in blacks with SCT.
