- 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 Type 2 Diabetes Mellitus
- Group 1 definition Diagnostic criteria applied to define the specific condition / phenotype represented in the case (exposed) group
- Patients with Type 2 Diabetes who were admitted to the First Affiliated Hospital of Zhengzhou University from October 2018 to October 2019; The diagnostic criteria of diabetes mellitus were as follows: (1) twice fasting plasma glucose ðFPGÞ ≥ 7:0 mmol/L, (2) twice oral glucose tolerance test (OGTT ≥ 11:1 mmol/L), and (3) diabetic symptoms (polyuria, thirst, drinking more water, and unexplained weight loss) accompanied with twice random blood glucose ≥ 11:1 mmol/L.
- Group 0 sample size Number of subjects in the control (unexposed) group
- 179
- Group 1 sample size Number of subjects in the case (exposed) group
- 137
- Antibiotics exclusion Number of days without antibiotics usage (if applicable) and other antibiotics-related criteria used to exclude participants (if any)
- long-term antibiotic application
