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
Suspected COVID-19 patients
Group 1 definition Diagnostic criteria applied to define the specific condition / phenotype represented in the case (exposed) group
Suspected COVID-19 cases without one of the following etiological or serological evidence:

(1) Fluorescence RT-PCR detects the positive of the COVID-19 virus nucleic acid. (2) Viral gene sequencing finds highly homologous to COVID-19 virus

Group 0 sample size Number of subjects in the control (unexposed) group
Group 1 sample size Number of subjects in the case (exposed) group
Antibiotics exclusion Number of days without antibiotics usage (if applicable) and other antibiotics-related criteria used to exclude participants (if any)
Receipt of antibiotics and/or probiotics within 8 weeks prior to enrollment

Lab analysis

Sequencing type Experimental technique used for quantifying microbial abundance
16S variable region One or more hypervariable region(s) of the bacterial 16S gene
Sequencing platform Manufacturer and experimental platform used for quantifying microbial abundance

Statistical Analysis

Statistical test Statistical test or computational tool used for differential abundance testing
Significance threshold p-value or FDR threshold used for differential abundance testing (if any)
MHT correction Have statistical tests be corrected for multiple hypothesis testing (MHT)?
LDA Score above Threshold for the linear discriminant analysis (LDA) score for studies using the popular LEfSe tool

Alpha Diversity

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