Box plot of the distribution of the 81 proteins analysed. The edges of the boxes indicate the 25th and 75th quantiles, including the middle 50% of the data; whiskers indicate the furthest points within 1.5 x IQR from the box. IQR is the interquartile range, defined as the difference between the 75th and 25th percentiles. For graphical purpose, the full names of the proteins have been abbreviated, as reported in Table S4. Protein level in y-axis is expressed as a normalized value (N.V.) on the basis of internal standard
