Alluvial plot showing changes in nasopharyngeal (NP) bacterial profiles among the 103 participants based on the most abundant bacterial genus detected at each preceding timepoint during the first year of life. Vertical bars at each timepoint represent the number of participants from which respective bacterial genera (shades of yellow: Actinobacteria; shades of red: Firmicutes, shades of blue: Proteobacteria, shades of pink: Fusobacteriota) were identified as most abundant. The proportion of participants with missing specimens at each timepoint is shown in gray. Specimen collection age (in months) and the number of specimens analyzed at each of the timepoints are denoted on the X-axis. Each participant is represented by a ribbon moving along the X-axis according to specimen collection age and Y-axis according to the most abundant bacterial genus detected at each of the timepoints. The color assigned to each participant ribbon is based on the most abundant bacterial genus detected at each preceding timepoint, highlighting sequential changes
