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

Obesity is a recognized factor influencing immune function and infectious disease outcomes. Characterization of the influence of obesity on SARS-CoV-2 humoral vaccine immunogenicity is required to properly tailor vaccine type (mRNA, viral-vector, protein subunit vaccines) and dosing schedule. Data from a prospective cohort study collected over 34 months was used to evaluate the slope of antibody production and decay and neutralizing capacity following SARS-CoV-2 vaccination in individuals with and without obesity at baseline. Most participants were female (65.4%), white (92.4%), and received mRNA vaccines. 210 were obese and 697 non-obese. Sex and infection-acquired immunity were identified as effect modifiers for the relationship between obesity and COVID-19 vaccine humoral immunogenicity. No consistent influence of obesity on peak titres, titre retention, antibody isotype (IgG, IgM, IgA), or neutralization was identified when controlling for other key variables. It may not be necessary to consider this variable when developing SARS-CoV-2 vaccine dosing strategies.
