Table reflects effect estimates of separate multivariable regression models using ISEL total score, ISEL subscales, and social network size score as exposure variables of interest. Data expressed as effect estimate [odds ratio (OR) or beta coefficient] and 95% confidence interval (CI). Significant effect estimates (p < .05) indicated in bold
^aModel 1 has prevalent CKD as the outcome. Analyses conducted on complete cases, n = 2671, and were adjusted for age, gender, income, education, body mass index, smoking status, diabetes, and hypertension
^bModel 2 has eGFR decline in ml/min/1.73m² per year as the outcome. Analyses conducted on complete cases, n = 1244 (participants with diabetes, hypertension or CKD at baseline), and were adjusted for age, gender, income, education, body mass index, smoking status, diabetes, and hypertension, albumin/creatinine ratio, and baseline eGFR
^cInterpersonal Support Evaluation List (ISEL) is a validated measure of functional social support
^dSocial network size is a measure of structural social support based on number and frequency of close contacts
