Recruitment to our microbiome study commenced in June 2018 and completed in December of 2018. The last batch of raw FASTQ sequences and raw taxonomy-level abundance summaries was received in October 2019. We had to spend more time on collecting and processing annotation data, ensuring quality, completeness, consistency and validity, and defining best approaches of dealing with"missing values".
We have now completed final data collection for the primary and secondary outcome measures.
