SARS-CoV-2 in early pregnancy-does it affect the aneuploidy screening markers and cause pregnancy loss?
Article in Irish journal of medical science, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundIt is known that vertical transmission of various infections poses a potential risk to the fetus, especially in early pregnancy. Potential effects of SARS-CoV-2 infection on early pregnancy and placental formation and functions still remain unknown.
aimTo determine the alterations of prenatal aneuploidy screening markers in a group of pregnant women who were SARS-CoV-2 positive during the first trimester. The secondary goal was to assess pregnancy loss rates.
methodThe study group consisted of pregnant women who were diagnosed with mild forms of SARS-CoV-2 infection before the screening test at any time in early pregnancy. The control group included pregnant women who were not diagnosed with SARS-CoV-2 infection during their pregnancy. SARS-CoV-2 infection was detected by RT-PCR in the nasopharyngeal swab samples. Multivariate linear regression analysis was performed due to evaluate effect of SARS-CoV-2 infection on NT and serum aneuploidy screening parameters taking maternal age and gestational age which the COVID-19 RT-PCR test result was positive into account.
resultsWe did not find any significant difference between the COVID-19-positive and COVID-negative groups in gestational age at screening, sonographic measurements of CRL, NT, and serum levels of PAPP-A, free hCG, and triple test serum markers even after accounting for maternal age and gestational age which the COVID-19 RT-PCR test result was positive. There was no statistically significant difference in pregnancy loss.
conclusionsWe did not find any evidence for unfavorable prenatal biochemical, ultrasound markers of fetal aneuploidy screening tests, and pregnancy loss rates in our study group.
