The image below shows the risks of intrauterine growth
restriction (IUGR) following maternal smoking either (A)
during the first trimester of pregnancy only, or (B) continued
throughout pregnancy relative to non-smokers.
An odds ratio indicates the probability of the outcome
occurring, where an OR=1 exposure does not have an effect,
OR>1 exposure is associated with higher odds of the
outcome, and OR<1 exposure is associated with lower odds.
Each bar represents findings from a separate study. The aim
of the study presented is to compare all studies published on
this topic to identify a consensus.
