Mean MSR (red line on each bar) and standard deviation of the values for each method. In this case, lower values are better; again, the positive or negative approach showed the best performance. The gray area represents the standard error of the mean (mean ± SEM) and the blue area is 1 standard deviation (mean ± SD) from the mean.
