Columns ii and iii refer to the number of TSSs within 100 kb of the A+/T+ boundary, upstream or downstream respectively. The figure of 67.0% (X) is significantly different from 50.0% using a binomial distribution approximated by the normal distribution, p < 10^{50}, n = 5908, z = 26, one tailed test.
