1 October 2002:

In the caption to Table 1, the first sentence was corrected from:

The genotype distribution of POAG patients were not significantly different from controls (χ²=1.150, degrees of freedom=2, p=0.5627), but there was a difference in the allelic distributions (χ²=0.559, degrees of freedom=1, p=0.4547).

to:

The genotype distribution of POAG patients were not significantly different from controls (χ²=1.150, degrees of freedom=2, p=0.5627). Similarly, there was no significant difference between the two groups in allelic distribution (χ²=0.559, degrees of freedom=1, p=0.4547).
