A cluster randomized controlled trial of a telephone-based parent intervention to increase preschoolers' fruit and vegetable consumption.

Further investigation to determine whether the intervention effect is maintained in the longer term is recommended. This trial was registered at http://www.anzctr.org.au as ACTRN12609000820202.
