Participant Flow

VDAART was a randomized, double-blind, placebo-controlled trial. Enrollment began October 2009 and completed follow-up January 2015 in 3 medical centers in the United Stated. 881 pregnant women age 18-39 at high risk for having children with asthma were randomized at 10-18 weeks gestation. 5 did not meet inclusion criteria and were removed.

We extracted DNA and sequenced the bacterial 16S V4 hyper-variable region. The average number of 16S region reads sequenced per participant is provided here. Prior evidence suggests that read counts of at least 1,000 are adequate for 16S fecal microbiome profiling (Reference: Momozawa Y, et cal.
