Low, rather than High, Body Mass Index Is a Risk Factor for Acute Kidney Injury in Multiethnic Asian Patients: A Retrospective Observational Study

Figure 5

Multivariate logistic regression models for studying the relationship between BMI and acute kidney injury at their first (number of patients with acute kidney injury [#AKIs] = 1075) and repeated (number of patients with no acute kidney injury [#AKIs] = 531) admissions during the 12-month cohort period. Note. BMI: body mass index; CI: confidence interval; OR: odds ratio. Adjusted variables in logistic regression models include age, gender, ethnicity, background diagnoses (cardiovascular disease, chronic kidney disease, diabetes mellitus, hepatobiliary disease, psychiatric illness, and gastrointestinal disease), primary diagnoses (infectious and parasitic diseases, neoplasm, diseases of the genitourinary system, diseases of the musculoskeletal system and connective tissue, and symptoms, signs, and ill-defined conditions), and procedures (otolaryngology related surgery, endoscopy, open laparotomy, and cardiology related percutaneous procedures).
