In secondary analyses stratified by prevalent diabetes, FABP4 was associated with a higher incidence rate of SCD in nondiabetic participants, (HR per SD of FABP4: 1.33 (95% CI: 1.07–1.65), P = 0.009) but not in diabetic participants (HR per SD of FABP4: 0.88 (95% CI: 0.62–1.27), P = 0.50), P for diabetes-FABP4 interaction 0.049 (Table 4). Here, FABP4 is linked to Schnyder corneal dystrophy.
