Findings In this cohort study of 7772 infants delivered during the COVID-19 pandemic, those born to the 222 mothers with a positive SARS-CoV-2 polymerase chain reaction test during pregnancy were more likely to receive a neurodevelopmental diagnosis in the first 12 months after delivery, even af...
(yes/no); 2) maternal chronic comorbidities measured in the year before pregnancy: hypertension, diabetes mellitus, asthma, depression or anxiety disorder and thyroid disorder defined by at least one ICD-9, ICD-10 code or at least one prescription filled for one of these conditions (Appendix 3...
For pre-existing DM, the sensitivity was 85.9% (95% CI 78.8 to 93.0) and the positive predictive value was 91% (95% CI 85 to 97) [35]. Similarly, a validation study conducted in Alberta found that ICD-10 codes for GDM in administrative databases can be used to reliably estimate the...
2–positive patients with theInternational Statistical Classification of Diseases and Related Health Problems, Tenth Revision(ICD-10) code U07.1 followed by a code for manifestation (eg,ICD-10code P23 for neonatal pneumonia).14AllICDcodes were captured in population-based health and quality registers...
The ICD-10 included codes for full-term delivery, premature delivery, and miscarriage. We additionally applied the behavior code for abortion as an outcome of pregnancy. We divided the pregnant individuals into two groups depending on the pregnancy outcome: live birth and failed to deliver. 2.3....
The second cohort included all non-pregnant women (aged 15-45) with a positive COVID-19 test. COVID-19 infection in pregnant or non-pregnant women was assessed using COVID-19 test results or ICD-10CM codeU07.1 from hospital data. COVID-19 severity was categorized based ...
If the strip test is positive, more detailed examinations of proteinuria are performed according to the Finnish Current Care Guidelines for gestational hypertension and preeclampsia.11 Information on isolated proteinuria was derived from the Hospital Discharge Register and the Medical Birth Register.

it is certainly possible that some patients with only a negative PCR result available at delivery were positive at an earlier point in pregnancy that was not captured with a PCR test; such undetected positivity among our control population would be more likely to bias our results toward the null...
