Comparison of the different fetal weight charts.
Our Tanzanian chart (—), the Hadlock chart [21] (-----), the Congolese chart [10] (…), the chart developed using the method suggested by Mikolajzcyk et al [20] modifying the Hadlock chart using local birth weights(–..–). One vertical line crosses at a GA of 35 weeks and 1 day indicating when the Tanzanian chart's 10th percentile deviates from the Congolese chart's and the Hadlock chart's 10th percentiles. One vertical line crosses at a GA of 37 weeks and 1 day indicating when the Tanzanian cohorts' 10th percentile deviates from the modified Hadlock chart's 10th percentile.
