The daily value was calculated for the specific trimester, and only for that trimester, and not extrapolated for the entire pregnancy.
We mention in the text if results of specific trimesters differ from those of the entire pregnancy either because the magnitude of the association is different and/or there is an exposure-response relationship observed in a specific trimester that is not observed for the entire pregnancy.
However, no clear evidence was found that this association was restricted to a specific trimester of exposure, or to prenatal exposure, as the risk of asthma was also increased in children whose mothers used paracetamol in the year after giving birth but not during pregnancy.
Thus, it is plausible that lead exposure may be particularly neurotoxic during a specific trimester.
The known dangers of fine particulate matter in the air, coupled with the researchers' ability to link higher autism risk to a specific trimester of pregnancy, makes it easier to a draw a clear link between autism and the air.
Some thought the recommendation specified provision during a specific trimester or only during the influenza season.
No specific trimester of ultrasound exposure or any combination of trimesters was associated with a significantly increased risk of CBT.
In the California study, there was no evidence for the trimester-specific effect estimates of PM2.5 (not adjusted for the other trimesters' levels) to be clearly stronger for one specific trimester (Parker et al. 2005).
Of the two-thirds of those who reported that they recommend the vaccine to their pregnant patients, either intermittently or routinely, the majority recommend the vaccine during the autumn/early winter period, or in a specific trimester (either first or third).
However there are a number of studies that report the prevalence of select activities during specific trimesters[ 3, 9, 11, 12] or at any time during pregnancy[ 3, 14, 15].
