The rate of death before day 28 was 13, whereas overall mortality rate was 18%. SNAP-II, SNAPPE-II, and mortality rates ↓ with increasing GA. Even within GA strata, risk of death ↓ with ↓SNAP-II and SNAPPE-II values. The PPV of most SNAP-II and SNAPPE-II cutoff levels were ~30%, especially in infants with SNAP-II >/=30.
