This post is intended for researchers by pointing to bacteria whose genetics are likely significant for long COVID. The raw data is below. Preliminary z-scores indicated that they are significant (Pr < 0.01) and no filtering has occurred for False Detection Rate. Users are advised to perform their own statistics.

Note: These results are lab-specific, using the data provided by BiomeSight.

The reference site for the study is: http://longcovid.microbiomeprescription.com/, the raw data is available at: http://citizenscience.microbiomeprescription.com/
