DART-FP1

The NTP Historical Control database for fetal defects from stand-alone prenatal development (i.e. teratology) studies or modified one generation studies (MOG) is provided here. Note that fetal findings (Column C) are broken up by exam type (Column A), followed by body area (Column B). Data is presented as the number of fetuses or litters with a finding and the percentage calculations are in parentheses. Rows in bold reflect the total number of fetuses or litters per finding. Columns labeled “TOTAL_FETUS” and “TOTAL_LITTER” indicate the total number of findings per fetus and per litter in all studies presented here. Columns labeled “MIN_FETUS”, “MIN_LITTER”, “MAX_FETUS”, and “MAX_LITTER” indicate the minimum and maximum number of fetuses or litters with that finding. The database will be updated as additional historical control information is obtained in NTP studies.
