Weight from Height. Shown in blue (male) and magenta (female) are median population height-weight data from 4 data sources: Pre-term infants [24] (INTERGROWTH Pre-Term), birth to 2 years WHO data [21] (WHO 45–110 cm, dashed), 5 to 10 years WHO data [21] (WHO 5-10yo), and 2 to 20 year CDC data [22] (CDC 2-20yo). The Population Median ‘reference’ derived from these data is shown in thick grey. The PBW Male/Female formulae used in the 2000 ARDS Network trial [19] is shown dotted (blue/magenta). The IBW reference used in the 1998 Stewart trial [13] is shown (dotted) in green
