Obligatorily acquired multimodal magnetic resonance imaging at registration with prespecified imaging conditions was assessed for cerebral microbleeds, white matter hyperintensities, enlarged basal ganglia perivascular spaces, or lacunes, and an ordinal SVD score was calculated (range, 0\u20134). Multivariable adjusting covariates were age, sex, hypertension, diabetes, dyslipidemia, current smoking, drinking, and estimated glomerular filtration rate (eGFR). Of 5324 patients (1762 women; median age, 73\u00a0years), 4797 (90.1%) patients were taking oral antithrombotic agents for secondary stroke prevention. Cerebral microbleeds were present in 32.7%, confluent white matter hyperintensities in 51.8%, extensive basal ganglia perivascular spaces in 38.9%, and lacunes in 59.4%. Median SVD score was 2. Compared with eGFR category G1 (eGFR \u226590\u00a0mL\/min per 1.73\u00a0m\n              <jats:sup>2<\/jats:sup>\n              ), adjusted odds ratios for SVD score increment were 1.63 (95% CI, 1.11\u20132.39) at category G4 (eGFR 15\u2013&lt;30\u00a0mL\/min per 1.73\u00a0m\n              <jats:sup>2<\/jats:sup>\n              ) and 2.05 (95% CI, 1.33\u20133.16) at G5 (eGFR &lt;15\u00a0mL\/min per 1.73\u00a0m\n              <jats:sup>2<\/jats:sup>\n              ). Corresponding odds ratios relative to urinary albumin\u2010to\u2010creatinine ratio (ACR) category A1 (ACR &lt;30\u00a0mg\/g) were 1.29 (95% CI, 1.12\u20131.49) for category A2 (ACR 30\u2013&lt;300\u00a0mg\/g) and 1.37 (95% CI, 1.05\u20131.77) for A3 (ACR \u2265300\u00a0mg\/g). When combined eGFR and ACR categories were assessed, risks for SVD score increment generally increased as eGFR decreased and ACR increased.\n            <\/jats:p>\n          <\/jats:sec>\n
