Differential abundance testing: associations between gut microbiota taxa at the genus level and positive affect/surgency, adjusted using covariates ¹.

Phylum	Family	Genus	Q Value for DESeq2 2	Q Value for ANCOMBC	Q Value for MaAslin
Firmicutes	Christensenellaceae	Christensenellaceae R-7 group	6.3 × 10−7	0.03	0.11
Firmicutes	Oscillospiraceae	UCG-002	6.3 × 10−7	0.03	0.11
Firmicutes	Peptostreptococcaceae	Clostridioides	1.0 × 10−3	0.11	0.16
Firmicutes	Ruminococcaceae	Subdoligranulum	8.7 × 10−4	0.23	0.22

¹ Model was adjusted for maternal education, maternal age, maternal race, pre-pregnancy BMI, gestational age, infant sex, birth weight, and infant age at IBQ-RVSF collection. ² Q-value is the FDR-adjusted p-value. Q-value < 0.001, 0.25, and 0.25 for multiple comparisons was considered statistically significant for DESeq2, ANCOM-BC, and MaAslin, respectively.
