Box Plot from Scientific Research

Boxplots depicting pathogen abundance in positive (+) versus negative () samples (labeled on X axis) defined based on culture. The boxes show the interquartile range and median line, and the whiskers show the variability extending to the furthest data points within 1.5 times above and below the interquartile range. Outliers outside of these ranges are shown as data points. Two-tailed t-test p-values for positive versus negative samples are shown above each plot. Red dashed lines indicate the detection threshold equivalent to 3 RPM.
