There was an error in Table 3 of this manuscript and some of the 25th and 75th percentile values were transposed. The corrected Table 3 is shown here.

In addition, there was an error in Table 4c for the community control group with prostate cancer. The 25th and 75th percentiles were transposed. The corrected Table 4c is shown here.
