The 2 groups were comparable for these parameters suggesting that there was no inherent selection bias in the subset group.

NS indicates not significant.

For the κ patients, n = 28 for the subset, and n = 270 for the database.

For the λ patients, n = 32 for the subset, and n = 915 for the database.
