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
Coronavirus disease 2019 (COVID-19) vaccines are highly effective but also induce adverse events, in particular, autoimmunity. Findings from several studies revealed that patients with life-threatening SARS-CoV-2 infection had increased, pre-existing, neutralizing antibodies against type I interferons (IFNs). However, whether COVID-19 vaccination induces the anti-type I IFN antibody remains unclear. In the current study, we evaluated plasma levels of 103 autoantibodies against various human self-antigens and 16 antibodies against viral antigens in healthy individuals pre- and post-COVID-19 vaccination. Twelve participants received a COVID-19 mRNA vaccine (Pfizer-BioNTech or Moderna), and 8 participants received a viral vector-based vaccine (Janssen). All participants produced increased antibody levels against SARS-CoV-2 antigens following vaccination. Among the 103 autoantibodies, only plasma levels of IgG autoantibodies against type I IFNs increased in participants who received a mRNA vaccine (3/12), but not in those who received the viral vector-based vaccine (0/8) at postvaccination compared to pre-vaccination. Among the three individuals showing increased anti-IFN IgG following vaccination, both plasma samples and plasma-purified total IgGs showed a dose-dependent binding ability to IFN-α; two of the three showed neutralizing activity to IFN-α-2a-induced phosphorated STAT1 responses in human peripheral blood mononuclear cells postvaccination compared to baseline in vitro. Among the 103 autoantibodies tested, the COVID-19 mRNA vaccine, but not the viral vector-based vaccine, specifically induced neutralizing anti-type I IFN autoantibodies in a small group of healthy individuals (~10%). Findings from this study imply that COVID-19 mRNA vaccines may suppress IFN-mediated innate immunity and impair immune defense through induced autoimmunity in some healthy individuals, who may need to switch to another type of COVID-19 vaccine (e.g., a viral vector-based vaccine).
