Huybrechts (Controls unexposed, NOS), 2023 Denmark, Finland, Iceland, Norway, Sweden and USA.
1996 - 2018
All pregnancies resulting in singleton live-born infants (for Nordic cohorts) and publicly insured mothers linked to their live-born infants (for USA). Pregnancies with 1 or more prescriptions of Ziprasidone during the first trimester, the period for organogenesis. unexposed (general population or NOS)
Pregnancies who did not fill any antipsychotic prescriptions during the 3 months prior to pregnancy until the end of the first trimester.
-9 / 6455324 Overlapping: Data of Huybrechts 2016 totally included in this larger study. Number of Ziprasidone exposures suppressed due to country-/data-specific small cell suppression policies.

Park, 2018 USA
2000 - 2010
Women who during the 3 months before their last menstrual period filled a prescription for one of the five most frequently used atypical antipsychotics: aripiprazole, olanzapine, quetiapine, risperidone, or ziprasidone. Pregnant women who had two or more prescriptions dispensed during the first 140 days of their pregnancy for Ziprasidone (also received before pregnancy). Exclusion if more than 1 studied antipsychotic. (This is a subgroup of exposure among the whole exposed group considered in the study). unexposed, sick
Pregnant women who had no prescriptions dispensed for an anti- psychotic medication during the first 140 days of pregnancy were classified as “discontinuers.”
140 / 431 Primary analyses performed individually for each substance (aripiprazole, olanzapine, quetiapine, risperidone, or ziprasidone).
Sorensen, 2015 Denmark
1997 - 2008
Pregnancies registered in the nationwide Danish registries from 1997 to 2008 (N = 1,005,319) Any prescription of Ziprasidone redeemed by the pregnant women during the exposure window, and recorded in the Danish National Prescription Register. (This is a subgroup of exposure among the whole exposed group considered in the study). unexposed (general population or NOS)
Unexposed women were defined as pregnant women who did not redeem any prescription of antipsychotic medications during the exposure window.
41 / 841183 Primary analyses performed on antipsychotics versus unexposed. Authors also analysed each antipsychotic (typical and atypical) substance separately.
