Group 0 name Corresponds to the control (unexposed) group for case-control studies: Individuals diagnosed with type 2 diabetes Mellitus

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: Patients 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.

Antibiotics exclusion Number of days without antibiotics usage (if applicable) and other antibiotics-related criteria used to exclude participants (if any): 3 months

16S variable region One or more hypervariable region(s) of the bacterial 16S gene: V3-V4

Data transformation Data transformation applied to microbial abundance measurements prior to differential abundance testing (if any).: relative abundances

Significance threshold p-value or FDR threshold used for differential abundance testing (if any): 0.05

MHT correction Have statistical tests be corrected for multiple hypothesis testing (MHT)?: No

Shannon Estimator of species richness and species evenness: more weight on species richness: increased

Simpson Estimator of species richness and species evenness: more weight on species evenness: unchanged
