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

Pre-existing neutralizing antibodies (NAbs) directed against vaccine vectors have attracted considerable research attention. Therefore, our aim was to establish a high-throughput economical neutralization assay to investigate the epidemiology of adenovirus type 2 (Ad2)-specific immunity in China and developed countries, including in a Chinese Human immunodeficiency virus (HIV)-1-infected population, and to guide the application of Ad2-vectored vaccines. We established a FluoroSpot-based anti-Ad2-virus neutralization assay using a recombinant replication-deficient Ad2 that expresses enhanced green fluorescent protein and standardized the critical parameters, including the choice of cell line, cell concentration, viral infective dose, and incubation time. The sera of 561 healthy individuals from China and developed countries and from 230 HIV-1-infected Chinese individuals were screened with this assay for Nabs against Ad2. The prevalence of anti-Ad2 NAbs was high in both China (92.2%) and developed countries (86.9%). Of the Ad2-seropositive individuals, 64.6% in China and 77.4% in developed countries had high NAb titers (> 810). The frequency of anti-Ad2 NAbs was higher in Anhui (97.5%) than in Beijing (88.7%). Their prevalence differed significantly according to age in Beijing, but not in Anhui Province, but by sex in neither province. Ad2 seroprevalence was as high among HIV-1-infected individuals (88.7%) as among healthy individuals (92.2%) in China. In conclusion, a simple, intuitive, high-throughput, economical fluorescence-based neutralization assay was developed to determine anti-Ad2 NAbs titers. Ad2 exposure was high in both healthy and HIV-1-infected populations in China, so vectors based on Ad2 may be inappropriate for human vaccines.
