A Clinical Trial of Change in Maternal Smoking and Its Effect on Birth Weight
Abstract
These clinical trial results are the first, to our knowledge, from a prospective, randomized, and controlled experiment demonstrating that a reduction of smoking during pregnancy improves the birth weight of the infant. Nine hundred thirty-five pregnant smokers were randomly assigned to treatment and control groups; the former received smoking intervention. At the eighth month of pregnancy, differences between the two groups in salivary thiocyanate level and reported smoking were statistically significant. For single, live births, the treatment group infants had a mean birth weight that was 92 g heavier and were 0.6 cm greater in length than the control group infants. The decrement in weight related to smoking cannot be fully explained by gestational age. The findings suggest that some fetal growth retardation can be overcome by the provision of antismoking assistance to pregnant women.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
