In the cited paper we used Bonferroni’s procedure to calculate the confidence intervals. However, we made a mistake when applying the formula for calculating the confidence coefficients by confusing division in tα/2m with multiplication (tα∗2m) during the calculation process. That is, we inadvertently used α × 2m instead of α ÷ 2m as the tail probability. The correct formula for calculating the confidence intervals is as follows:
