1 · What the graph read from it

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.

2 · The registry

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

The coronavirus disease 2019 (COVID-19) vaccine generates functional antibodies in maternal circulation that are detectable in infants, while the information is restricted to the usage of COVID-19 vaccine during pregnancy. In this study, we aimed to evaluate the effect of maternal COVID-19 vaccines before pregnancy. Infants were included from mothers with no inactivated COVID-19 vaccine, 1-, 2-, and 3-dose before pregnancy, and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) immunoglobulin G (IgG) antibodies were tested. Comparative analysis was done between the groups. A total of 130 infants were enrolled in the study. Significantly higher levels of SARS-CoV-2 IgG antibodies in infants born to mothers with 3-dose COVID-19 vaccine before pregnancy compared with 1- and 2-dose groups (p < 0.0001). The levels of antibodies decreased significantly with age in infants born to mothers with the 3-dose COVID-19 vaccine before pregnancy (r = -0.338, p = 0.035), and it was still higher than that 2-dose COVID-19 vaccine group. The maternal SARS-CoV-2 antibodies produced from the inactivated COVID-19 vaccine before pregnancy can be transferred to newborns via the placenta. Maternal immunization with 3-dose of the COVID-19 vaccine before pregnancy could be more beneficial for both mothers and infants.
