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

Despite more than 50 years of vaccination, disease caused by the bacterium Bordetella pertussis persists, with rates increasing in industrialized countries over the past decade. This rise may be attributed to several factors, including increased surveillance, emergence of vaccine escape variants, waning immunity in adults, and the introduction of acellular subunit vaccines, which include chemically detoxified pertussis toxin (PTd). Two potently protective epitopes on pertussis toxin (PTx) are recognized by the monoclonal antibodies 1B7 and 11E6, which inhibit catalytic and cell-binding activities, respectively. In order to determine whether the PTx exposure route affects antibody responses to these epitopes, we analyzed sera from 30 adults with confirmed pertussis exposure and from 30 recently vaccinated adults for specific anti-PTx antibody responses and in vitro CHO cell neutralization titers. While overall titers against PTx and the genetically detoxified variant, PTg, containing the R9K and E129G substitutions, were similar in the two groups, titers against specific epitopes depended on the exposure route. Natural infection resulted in significantly higher titers of anti-PTx-subunit 1, 1B7-like, and 11E6-like antibodies, while acellular vaccination resulted in significantly higher titers of antibodies recognizing PTd. We also observed a correlation between in vitro protection and the presence of 1B7-like and 11E6-like antibodies. Notably, chemical detoxification, as opposed to genetic inactivation, alters the PTx tertiary and quaternary structure, thereby affecting conformational epitopes and recognition of PTx by 1B7 and 11E6. The lower levels of serum antibodies recognizing clinically relevant epitopes after vaccination with PTd support inclusion of PTg in future vaccines.
