Heart rate characteristics (HRC) index and neonatal sequential organ failure assessment (nSOFA) scores at nine time points surrounding the time of blood culture (time 0) in events diagnosed as late-onset sepsis (LOS) or necrotizing enterocolitis (NEC) for patients who died during the episode compared with those who survived. (A) The HRC index was higher for infants who died during LOS or NEC from the time of blood culture to 24 hours after (*p < 0.05). (B) nSOFA was higher for infants who died during LOS or NEC at all time points analyzed (*p < 0.01).
