Continuous variables were compared using the Student’s t-test and presented as mean ± standard deviation. Categorical variables were compared using the χ2 test and presented as number and percentage. CGA, corrected gestational age; CPAP, continuous positive airway pressure; CMV, conventional mechanical ventilation.
