Box Plot from Scientific Research

Mean fluorescence intensity (MFI) of surface CD4 expression of cells from patients in the I2 PSC group (n = 6). Significance was determined using a double-sided Wilcoxon matched-pairs signed-rank test without adjustment for multiple comparisons (n = 6). The center line represents the median; the hinges indicate the first and third quartiles; the upper and lower whiskers extend to the largest and smallest values that are within 1.5 times the IQR from the first and third quartiles, respectively (a, b).
