Response to: 'Causal association of gut microbiome on the risk of rheumatoid arthritis: a Mendelian randomisation study' by Lee

I am grateful to Dr Young Ho Lee1 for response to my article.2 Although my study demonstrated non-causal association between gut microbiome and the risk of rheumatoid arthritis (RA), the author demonstrated significant association between them.\n\nFirst, the reason why different conclusions were drawn from two studies is that I extracted only ‘Gut microbiota (bacterial taxa) (unit decrease)’ from variables of exposures in harmonised dataset before conducting Mendelian randomisation (MR) (R script is …
