- Homo sapiens
- Body site Anatomical site where microbial samples were extracted from according to the Uber Anatomy Ontology
- Tongue Glossus,Tongue,tongue
- Condition The experimental condition / phenotype studied according to the Experimental Factor Ontology
- Severe aplastic anemia SAA,Severe aplastic anemia,severe aplastic anemia
- Group 0 name Corresponds to the control (unexposed) group for case-control studies
- engraftment
- Group 1 name Corresponds to the case (exposed) group for case-control studies
- hematopoietic stem cell transplantation 100 days after the transplant
- Group 1 definition Diagnostic criteria applied to define the specific condition / phenotype represented in the case (exposed) group
- In HSCT patients, The first sample was obtained before transplant conditioning treatment. The second specimen was collected at engraftment, defined as two absolute neutrophil counts of greater than 500 per microliter for at least 2 days. The final specimen collection occurred at the participant’s scheduled clinic visit approximately 100 days following transplant.

- 4
- Group 1 sample size Number of subjects in the case (exposed) group
- 4
