There was no statistically significant difference in reintubation rate ( noninvasive positive-pressure ventilation group , @ % ; inhaled oxygen group , @ % ; p > @ ) and length of stay ( days ) in PICU ( noninvasive positive-pressure ventilation group , @ -LSB- @-@ -RSB- ; inhaled oxygen group , @ -LSB- @-@ -RSB- ; p > @ ) or hospital ( noninvasive positive-pressure ventilation group , @ -LSB- @-@ -RSB- ; inhaled oxygen group , @ -LSB- @-@ -RSB- ) .
