Risk of vertical transmission of SARS CoV-2 infection to neonates born to covid positive mothers: A pilot study from a tertiary care hospital of North India.

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
objectivesTo assess the risk of neonatal SARS-CoV-2 infection born to the women with confirmed SARS-CoV-2 infection. MATERIALS AND
methodsThis prospective study was conducted at single tertiary hospital from September 2020 and May 2021. 50 pregnant women with confirmed SARS-CoV-2 infection and 50 neonates were included for analysis. We performed comprehensive testing of all biological samples for vertical transmission including the cord blood immunoglobulin.
resultsWe detected SARS-CoV-2 in one fetal membrane and one amniotic fluid sample. We also demonstrated presence of anti-SARS-CoV-2 IgM antibodies in cord blood of 3 neonates. Though none of the samples of vaginal secretion, breast milk and nasopharyngeal swab from neonates were tested positive for covid infection via RT-PCR. We demonstrated presence of anti-SARS-CoV-2 IgG antibodies in the cord blood which had shown positive correlation with increasing disease to delivery interval and disease severity.
conclusionVertical transmission of SARS-CoV-2 is possible. As virus was not detected in cervicovaginal secretions and breast milk so vertical transmission through this mechanism seems unlikely. Presence of IgG in cord blood is suggestive of passive immunity acquired from mother. This finding has greater clinical implication as large number of expecting mothers are being vaccinated.
