Figure 2. Association between taxa abundance and cognitive impairment among all women and according to HIV serostatus.
Taxa were identified using ANCOM-II adjusting for age, race, education, poverty, recreational drug use, HCV, site, antibiotics, smoking, viral load and ART use (among HIV+) as appropriate. Logistic regression was used to show OR of cognitive impairment by relative abundance of taxa, adjusting for above covariates used in ANCOM-II. Relative abundance were CLR-transformed. P for interaction<0.05 for Eubacterium, Veillonella, Eubacterium biforme and Ruminococcus bromii. Taxa were ordered by OR at genus and species level, respectively.
