OR = odds ratios; 95% CI = 95% Confidence Interval; ORs were computed from logistic regression models for association between tear thickness (no tear as reference group) and fatty infiltration (Grade >= 1); Unadjusted ORs represent models with only tear thickness as independent variable: Adjusted ORs represent models that were additionally adjusted for BMI, sex, and participant age at baseline
