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

backgroundClostridioides difficile infection (CDI) is a major healthcare challenge that is associated with high morbidity and mortality. Current diagnostic methods are limited in terms of specificity and invasiveness, necessitating novel, non-invasive imaging techniques. In this study, we develop and evaluate an immunoPET radiotracer targeting C. difficile toxin B for in vivo detection of CDI in a murine model.

resultsThe monoclonal antibody bezlotoxumab, was radiolabeled with [

conclusionsWe successfully developed an immunoPET radiotracer targeting toxin B for detection of CDI. Its application in an animal CDI model proved its capacity to detect the source of infection with high specificity, while avoiding confusion with non-specific inflammation.
