Abstract
The findings indicate that premature infants exposed to CL experience substantially less LOS and more weight gain than their peers exposed to either DL or CBL. As premature infants require CL exposure after discharge, its implementation in the neonatal intensive care unit should be transitional and timed appropriately. Notably, the studies included in this meta-analysis used small sample sizes and were affected by a number of quality concerns. Thus, large-scale studies should be conducted to confirm the optimal duration of CL exposure for premature infants in neonatal intensive care units.
