Mean is the total mean of the mean standard deviation of three consecutive readings from the same infant. SD is the standard deviation of the standard deviations of three consecutive readings from the same infant. CV is calculated as (SD/Mean)*100 for each infant, and mean CV % is the mean CV%s, while SD CV% is the standard deviation of CV%s.
