We also re\u2010examined the neutrophil\u2010to\u2010lymphocyte ratio (NLR) as a candidate inflammatory marker.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Cross\u2010sectional analysis of 1107 adults with diabetes from the National Health and Nutrition Examination Survey (NHANES) 2005\u20132008. Three sequential logistic regression models were fitted: Model 1 (unadjusted), Model 2 (metabolic covariates), and Model 3 (Model 2 plus log\u2010transformed urinary albumin\u2010to\u2010creatinine ratio [UACR]). A mediation analysis with 2000 bootstrap resamples estimated the proportion of the albumin\u2013DR association attributable to the UACR pathway in participants with HbA1c\u2009\u2265\u20097.0%. Sensitivity analyses applied the NHANES sampling weights, strata, and primary sampling units.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      DR was present in 356 of 1107 participants (32.2%; 29.0% after weighting to the U.S. population). Each 1\u2009g\/dL increase in serum albumin was associated with a 39% reduction in the odds of DR in the unadjusted model (OR 0.61, 95% CI 0.41\u20130.89). The association attenuated after adjustment for metabolic and renal covariates (Model 3 OR 0.82,\n                      <jats:italic>p<\/jats:italic>\n                      = 0.399).

The indirect association through UACR was statistically significant (OR 0.79, 95% CI 0.61\u20130.92; bootstrap\n                      <jats:italic>p<\/jats:italic>\n                      &lt; 0.001), giving a proportion mediated of 34.4%.

The design is cross\u2010sectional, so the temporal ordering assumed by mediation analysis cannot be verified and these estimates remain associational. Low albumin in this setting should still prompt assessment of the kidney and the retina at the same visit.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1155\/joph\/6568455","type":"journal-article","created":{"date-parts":[[2026,9,16]],"date-time":"2026-09-16T07:40:29Z","timestamp":1789544429000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Serum Albumin as a Marker of Microvascular Burden in Diabetic Retinopathy: Mediation by Diabetic Nephropathy in Uncontrolled Diabetes"],"prefix":"10.1155","volume":"2026","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-6526-065X","authenticated-orcid":false,"given":"Yabing","family":"Zhang","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-6389-5120","authenticated-orcid":false,"given":"Jin","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6140-9868","authenticated-orcid":false,"given":"Qiuli","family":"Yu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-2575-9456","authenticated-orcid":false,"given":"Xinjun","family":"Xue","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-4525-8471","authenticated-orcid":false,"given":"Li","family":"Yuan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,9,16]]},"reference":[{"key":"e_1_2_12_1_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.apjo.2024.100109"},{"key":"e_1_2_12_2_2","article-title":"Global Estimates on the Number of People Blind or Visually Impaired by Diabetic Retinopathy: a meta-analysis from 2000 to 2020","volume":"38","author":"Leasher J.
