Gender-specific, weight-adjusted z-scores of left ventricular m-mode measurements (including LV mass) for use on premature babies up to 2 kg.

Because weight is a practical measurement in preterm infants and our analysis found that length or BSA were not superior indexes, we propose that weight be used as the index for LV dimensions in small premature infants.
