Box Plot from Scientific Research

A plot depicting the background subtracted frequencies of activated T cells. The horizontal lines represent medians, the bounds of the boxes indicate the 25th and 75th percentiles and the whiskers represent the minima and maxima. Each dot represents an individual sample (controllers, n = 53; progressors, n = 61). The P value was calculated using the MannWhitney U -test (two sided). Note that some samples are from the same participant collected at different study timepoints.
