Means, SDs, and smoothed percentiles for birth weight (g) for gestational age within the corrected dataset: US male singleton live births (2009 to 2010). The corrected dataset uses both last menstrual period (LMP) and clinical/obstetric-based estimates of gestational age, and reflects the application of the Basso and Wilcox algorithm^[1] to correct likely errors in gestational age and excludes implausible birth weights for gestational age.

SD: standard deviation.
