Figure 2: Variation in enteral iron exposure in the first 28-days by recruitment site.

Figure 2:

The study cohort was separated into those patients who had no enteral iron exposure in the first 28-days with the remaining patients divided into quartiles by total exposure in mg per kg. Deidentified PENUT Trial sites (1 through 19) are noted on the far left and number of patients recruited at each site at the far right.

Significant site to site variation in exposure to enteral iron is seen in the first 28-days, with some sites (#3, #7, #11, 17) having a majority of recruited patients not receiving any enteral iron in the first 28-days after birth.
