- Condition The experimental condition / phenotype studied according to the Experimental Factor Ontology
- Delivery measurement Delivery measurement,delivery measurement
- Group 0 name Corresponds to the control (unexposed) group for case-control studies
- Vaginal mode of delivery during early transmission - Transmission vs Vaginal mode of delivery during early transmission - No Transmission
- Group 1 name Corresponds to the case (exposed) group for case-control studies
- Caesarean section (CS) mode of delivery during early transmission - Transmission vs CS mode of delivery during early transmission - No Transmission
- Group 1 definition Diagnostic criteria applied to define the specific condition / phenotype represented in the case (exposed) group
- Babies delivered by caesarean section exhibit markedly reduced rates of maternal microbial strain transmission in comparison to those delivered vaginally, as well as a persistent depletion of Bacteroides species and other commensals.
- Group 0 sample size Number of subjects in the control (unexposed) group
- 35
- Group 1 sample size Number of subjects in the case (exposed) group
- 24
