For SGA births, three categorizations were evaluated: births weighing <5th and <10th percentiles based on sex- and race-specific weight by gestational week norms from New Jersey and births weighing less <10th percentile based on sex-specific growth curves for California [ 4, 9].
We divided this score into three equal classes of wealth based percentiles, that is, less than 33.33th percentile (low, i.e. poorest), 33.33 to 66.66th percentile (medium, i.e. moderately rich), and more than 66.66th percentile (high, i.e. richest).
For the purposes of the present study we used the following percentiles: "underweight": Less than the 5th percentile, "healthy weight": 5th percentile to less than the 85th percentile, "overweight": 85th to less than the 95th percentile, and "obese": Equal to or greater than the 95th percentile [ 19].
In addition, it would be reasonable to establish severity criteria according to BMI percentiles (mild, moderate, severe, and extreme, probably corresponding to the 10th, 3rd, 1st, and less than 1st percentile, respectively) similar to those formulated in adult AN [ 14].
This, along with counties in the expansion state that are less than 75th percentile of the poverty rate, will make up the control group.
Regardless, for 4 h pressing time the requirement in the EN 13353 [16] to the 5th percentile less as it was fulfilled for all treatments, featuring polyurethane as a structural adhesive for this pressing time.
Shown in parentheses are the number of haplotypes with p-value less than 0.001 (>99.9th percentile).
Neither study detected 2,4-D at the 50th percentile (less than 1 parts per billion, ppb).
The proportion of children with birth weight less than 10th percentile was 58.05%.
When compared these rates since 2007 with other countries it was less than 50 percentile.
