From: Longitudinal gut virome analysis identifies specific viral signatures that precede necrotizing enterocolitis onset in preterm infants

a, Virus family relative abundance in samples from control infants, grouped by PMA. Multiple pie charts within a square indicate multiple samples from the same infant in one week. b, Viral contig richness and alpha diversity (Shannon index) in control samples over time. Trend lines and 95% confidence bands were generated using LOESS smoothing in R. Smoothing level: span = 0.5. c, Median weighted Bray–Curtis dissimilarity within individual control infants and between individual control infants, n = 14 infants. Box limits, 25th and 75th percentiles; whiskers, 2.5 and 97.5 percentiles. Statistical significance was assessed by two-sided Mann–Whitney U-test, P < 0.0001. d, PCoA of control samples, using weighted Bray–Curtis distance. Statistical significance of PMA (continuous variable) was assessed by PERMANOVA. Samples were colour-coded by PMA.
