*
No RS: no respiratory support; NI-RS: Non-invasive respiratory support; I-RS: Invasive respiratory support; Mixed RS: invasive +non-invasive respiratory support.
**
Logistic regression models were used to compare infants who received I-RS and Mixed RS to the NI-RS group. Similarly, infants who received I-RS were compared to those received mixed RS.
