- Group 0 name Corresponds to the control (unexposed) group for case-control studies
- Healthy controls
- Group 1 name Corresponds to the case (exposed) group for case-control studies
- Individuals diagnosed with peripheral neuropathy associated with type 2 diabetes
- Group 1 definition Diagnostic criteria applied to define the specific condition / phenotype represented in the case (exposed) group
- Individuals diagnosed with peripheral neuropathy associated with type 2 diabetes; The criteria for DPN were as follows: spontaneous limb pain, symmetrical or unilateral limb numbness, sensation of dullness and body tension, muscle weakness, weakened or absent tendon reflexes, and significant decreases in sensory and motor nerve conduction velocities as revealed via electromyography indicating the positive involvement of two or more nerves and normal arterial pulses in the foot and back.
