Fig. 5: α-diversity before and after the first antibiotic treatment in infants with CF.
From: Early nasal microbiota and subsequent respiratory tract infections in infants with cystic fibrosis

Shannon-diversity index (SDI) was compared in a generalized additive mixed model before and after the first antibiotic treatment (635 swabs from 33 infants). Displayed are the model fitted SDI values on the y-axis and the time to first antibiotic treatment on the x-axis. Swabs taken before the first antibiotic treatment (n = 241) are displayed in red and after in green (n = 394). The trendlines (loess function) are displayed with 95% confidence intervals (gray shadings).
