Multinomial regression showing the baseline association of urine biomarkers of kidney tubule injury and dysfunction with frailty index status (each modeled as “per 2-fold higher” with frailty compared with fit older adults [less fit group omitted]). Models were adjusted for age, sex, race, BMI, alcohol use, years of education, insurance status, SBP and DBP, smoking status, urine creatinine, eGFR, and albuminuria. IL-18, interleukin-18; KIM-1, kidney injury molecule-1; NGAL, neutrophil gelatinase-associated lipocalin; MCP, monocyte chemoattractant protein-1; β2M, β2-microglobulin; A1M, α1-microglobulin; Umod, uromodulin.
