Distribution of the polyomavirus peptide microarray signals in function of the the viral proteins. Values on the Y-axis are expressed as log2(signal of sample/signal of the no-sample control), making a value of 0 = background. From the statistics for all 4284 datapoints: median: 1.593 (dashed line); 75th percentile: 2.129 (dotted line). The following median values, respectively from left (LTAg) to right (agno), were found: 1.68, 2.33, 1.58, 1.33, and 1.41. The median value from one protein was compared to the median value all other proteins by using a “Linear Rank test for two samples”. The estimated difference between the medians (= median test protein minus median all other datapoints), the lower (LCI) and upper (UCI) 95% confidence intervals, and the p-values are as follows: 1) LTAg – others: 0.10, LCI: 0.032, UCI: 0.157, p = 0.0006; 2) stAg – others: 0.76, LCI: 0.587, UCI: 0.866, p = 3.45E-23; 3) VP1 – others: -0.05, LCI: -0.108, UCI: -0.005, p = 0.02712; 4) VP2 – others: -0.31, LCI: -0.360, UCI: -0.260, p = 4.44E-16; and 5) agno – others: -0.20, LCI: -0.323, UCI: 0.129, p = 0.2727.
