Infant Passive Protection Against Coronavirus Through Exclusive Breastfeeding: A Cross-Sectional Study.
Article in Nutrients, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
BACKGROUND/
objectivesThis study aimed to determine the percentage and duration of neutralizing antibodies against the Omicron variant in human milk after vaccination against SARS-CoV-2, considering the three different vaccine technologies approved in Brazil.
methodsA cross-sectional study was conducted with lactating women who received the complete vaccination cycle with available vaccines (AstraZeneca, Pfizer, CoronaVac, and Janssen). The participants resided in Rio de Janeiro, and samples were collected from April to October 2022. Breast milk was analyzed for evidence of neutralizing antibodies using specific assays for the Omicron variant.
resultsThe results showed that all types of vaccines were effective in inducing neutralizing antibodies in breast milk regardless of the vaccine technology used. There was no significant difference between women receiving two or three doses. Exclusive breastfeeding was significantly associated with higher percentages of neutralizing antibodies in breast milk compared to non-exclusive breastfeeding.
conclusionsThese findings reinforce the importance of breastfeeding as a strategy to provide passive protection to infants, especially where vaccination for children under six months of age is not recommended.
