*3.1. Subject Demographics*

Eighteen subjects were enrolled and recorded in the study for the period of 2016–2017; one was excluded from final analysis due to conflicting documentation. At the time of recording, all infants were under the chronologic age of 10 weeks and had corrected gestational ages of 33–40 weeks. The mean age of patients at time of recording was 5 weeks and 35.5 weeks adjusted. The mean gestational age at birth was 30 weeks and 3 days. The population was 65% male and included a variety of racial backgrounds, with the largest group being White at 35%. Race was defined per electronic medical record with Asian including individuals of Indian and Southeast Asian descent. All subjects had various comorbidities of prematurity, with the prevalence of the most pertinent—apnea of prematurity, history of respiratory distress syndrome, chronic lung disease, and anemia of prematurity—demonstrated in Table 1.
