Effects of SARS-COV-2 infection on fetal pulmonary artery Doppler parameters.
Article in Echocardiography (Mount Kisco, N.Y.), 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
purposeTo determine the effect of SARS-CoV-2 infection on the fetal pulmonary system using the acceleration time (AT), ejection time (ET), and acceleration/ejection time ratio (PATET) of the fetal main pulmonary artery Doppler waveform.
methodsWe prospectively studied pregnant women attending our hospital with confirmed SARS-CoV-2 infection by RT-PCR test and an age-matched control group who admitted for routine prenatal care. An ultrasound examination that included measurements of the AT, ET, and AT/ET ratio (PATET) were performed and the results were compared.
resultsFifty-five SARS-CoV-2-infected and 93 control group pregnant women were included in this study. AT found higher in the COVID-19 positive group when compared with controls. When the ET and PATET parameters were compared, no differences were detected between the groups. Eleven neonates had Neonatal Intensive Care Unit (NICU) requirement in the COVID-19 positive group while there were none in the control group. All fetal pulmonary artery Doppler values were decreased in NICU admitted fetuses. The mean gestational week of this group was lower than non-NICU COVID-19 positive group and the control group.
conclusionCOVID-19 infection increases fetal pulmonary blood flow, which appears high AT values on Doppler parameters. NICU admission only occurred in the COVID-19 group and their Doppler values were found significantly lower than non-NICU COVID-19 group. The clinical significance of this result must be evaluated with further studies.
