BCL2 and bronchopulmonary dysplasia: Moreover, the expression trend of cleaved caspase‐3, Bax, and Bcl‐2 at P70 were consistent with those at P14 (F(2,9)=26.43, p = 0.0002 for treatment; p = 0.0001 for BPD + NS vs. CON and p = 0.0017 for BPD + NS vs. BPD + ROS in Figure 4L; F(2,9)=51.50, p < 0.0001 for treatment; p < 0.0001 for BPD + NS vs. CON and p < 0.0001 for BPD + NS vs. BPD + ROS in Figure 4M; F(2,9)=22.94, p = 0.0003 for treatment; p = 0.0002 for BPD + NS vs. CON and p = 0.0280 for BPD + NS vs. BPD + ROS in Figure 4N).
