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 human respiratory syncytial virus (RSV) is a leading cause of severe respiratory infections in newborns, young children, immunocompromised patients, and older adults. The current landscape of approaches to preventing the RSV disease includes vaccines for older adults and pregnant women, as well as prophylactic monoclonal antibodies for newborns and infants, with positive results. To expand the availability of prophylactic options against the RSV disease for vulnerable individuals, including newborns and older adults, we developed a recombinant BCG-based vaccine expressing the RSV nucleoprotein (rBCG-N-RSV) and manufactured under Good Manufacturing Practice (GMP) conditions. This vaccine has previously been shown to be safe and immunogenic in murine models, in neonatal calves, and has completed a phase 1 clinical trial in human adults. This article aims to assess the quality control testing of a GMP lot of rBCG-N-RSV to ensure antigen expression, potency, safety, and efficacy, which are required to advance to further clinical trials. Notably, all these parameters complied with release requirements. Furthermore, vaccine safety and protection were evaluated in a murine model of RSV infection, demonstrating enhanced virus-specific CD4
