  We investigate the possible large extra dimensions (LED) effects induced by
the Kaluza-Klein gravitons up to the QCD next-to-leading order (NLO) on $ZZW$
production at the large hadron collider (LHC). The integrated cross sections
and some kinematic distributions are presented in both the standard model (SM)
and the LED model. The numerical results demonstrate that the NLO QCD
corrections are sizeable and remarkably reduce the leading order (LO) LED
effect depending strongly on the phase space. The NLO LED relative
discrepancies of the total cross section could become sizable for the $ZZW$
production, if we apply proper event selection criteria. We find that the LO
result overestimates the LED effect and is insufficient to provide a believable
theoretical prediction.
