Group 0 name Corresponds to the control (unexposed) group for case-control studies
Salivary Microbiome pre treatment
Group 1 name Corresponds to the case (exposed) group for case-control studies
Salivary Microbiome post treatment
Group 1 definition Diagnostic criteria applied to define the specific condition / phenotype represented in the case (exposed) group
Changes in the oral microbiome from pre- to post-treatment saliva collected from patients with SCC at diagnosis and 6 months later (0 and 6 months), to identify changes that occurred soon after completion of therapy.
