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.
Group 0 sample size Number of subjects in the control (unexposed) group
14
Group 1 sample size Number of subjects in the case (exposed) group
45
Antibiotics exclusion Number of days without antibiotics usage (if applicable) and other antibiotics-related criteria used to exclude participants (if any)
3 months
