APLS, advanced pediatric life support.
Values are percentages of weight estimates within specified limits of deviation from actual weight.
†
Underweight/normal and overweight/obese were defined as < and > 85th percentile for weight-for-length percentiles among infants aged <2 y and for BMI-for-age percentiles for among children aged 2–5.9 years, respectively.
