Kidney measurements with a verifiable laboratory-report-to-image interval of no more than 7 days were retained. Exact urinary albumin-to-creatinine ratio (UACR) values were analyzed after log2 transformation; eGFR was recalculated using the 2021 Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) creatinine equation. Eight vascular outcomes were analyzed at the eye level using patient-clustered robust standard errors. The prespecified primary analyses were separate core models for UACR and eGFR adjusted for age, gender, body mass index, diabetes duration, HbA1c, and systolic blood pressure, with Benjamini\u2013Hochberg false discovery rate (FDR) correction across the eight outcomes within each exposure family. Joint, complete-case, alternative-equation, restricted-range, categorical, spline, and tighter-temporal-window analyses were treated as supportive or exploratory.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The final cohort included 658 eyes from 337 patients; the median absolute laboratory-report-to-image interval was 1 day (IQR, 0\u20131), and 97.9% of eye records were within 3 days. In the primary separate core models, neither UACR nor 2021 CKD-EPI eGFR was associated with any of the eight vascular outcomes after FDR correction (minimum\n                      <jats:italic>q<\/jats:italic>\n                      \u00a0=\u00a00.090). UACR showed a nominal association with arterial density (\n                      <jats:italic>q<\/jats:italic>\n                      = 0.097), and eGFR showed nominal associations with overall, arterial, and 3-mm foveal vessel density. Exploratory complete-case analyses yielded stronger eGFR signals: in the 431-eye\/220-patient joint complete-case cohort, the eGFR-only model in the same cohort was FDR-significant for all eight outcomes, and seven remained significant after mutual adjustment with UACR. Alternative-equation and restricted-range analyses also yielded eGFR-related associations, whereas same-day analyses were imprecise and null.

Exploratory complete-case and sensitivity analyses suggested a model-dependent eGFR-related pattern, whereas UACR remained largely null.
