TABLE 2

Weight gain

As growth is fairly linear during the first 6 weeks of life, trajectories of weight gain were calculated as a measure of growth. Each trajectory represents the mean of a group. As birth weights are dissimilar, statistics were not performed. The table is only intended to show trends.

Name of groupAverage weight gain trajectory
WTy = 63.9x + 152.9
IUTx32/45y = 34.9x + 154.1
IUTx45.1y = 58.6x + 165.9
IUTx.45.2y = 36.6x + 99.6
IUTx55y = 48.2x − 50.2
XLHEDy = 47.2x + 67.2
