Altered Intracellular ATP Production by Activated CD4+ T-Cells in Very Preterm Infants

Table 2

Characteristics at birth of infants enrolled in the study: median (range); GA: gestational age; SGA: small for gestational age; AGA: appropriate for gestational age; : prolonged Premature Rupture of Membranes: a case of premature rupture of membranes in which more than 18 hours has passed between the rupture and the onset of labor/delivery.
