Study flow chart.

Study flow chart of 285 marginally low birth weight (marginally LBW) infants and 95 control children born with normal birth weight (NBW). Four infants were excluded due to congenital disorders. Four of the marginally LBW children did not attend the 3.5 year visit but did attend the 7 year visit. The marginally LBW children were also stratified for being born small- or appropriate for gestational age (SGA and AGA respectively).
