Differences in alpha diversity between RP/post-RP and non-COV. (a) Forest plot of the differences in Shannon’s diversity index between RP/post-RP and non-COV. (b) Forest plot of the differences in observed species between RP/post-RP and non-COV. (c) Boxplots showing standardized Shannon’s diversity index by SARS-CoV-2 infection status (red = COV, purple = RP, blue = post-RP, and green = non-COV). COV, samples derived from COVID-19 patients; RP, samples derived from COVID-19 recovered patients who with clearance of SARS-CoV-2 RNA (negative conversion of viral RNA) within one month; those with negative conversion of viral RNA more than three months were especially grouped as post-RP; non-COV, samples derived from non-COVID-19 individuals
