Figure 1.
Time curves of the proportion of infants receiving a given nutritional component Time is expressed as postmenstrual age in weeks. Curves are stratified and colour-coded by infant gestational age groups (GA), computed on the set of infants still in care at a given postmenstrual age. The vertical grey dashed line indicates 36 weeks postmenstrual age. In (a–f) we show the proportion of infants who are still in care at a given postmenstrual age receiving each of the six components (MM: Maternal Milk, HDM: Human Donor Milk, BMF: Breast Milk Fortifier, FM: Formula Milk, PN: Parenteral Nutrition, GE: Glucose Electrolyte solution). We only considered GA > 22 weeks as, due to small sample size, values for GA = 22 weeks exhibited too much variation for meaningful interpretation.
