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

Influenza A virus (IAV) is a highly infectious enveloped RNA virus that primarily causes respiratory disease. Continuous antigenic variation in influenza virus hemagglutinin (HA) is a major driver of influenza pandemics. Therefore, precise identification of B-cell epitopes within HA is essential for developing diagnostic tools and vaccine candidates that can help limit further influenza spread. In the present study, an integrated experimental and bioinformatics strategy was used. A trimeric HA protein was rationally designed to improve antigenicity and immunogenicity, expressed in a mammalian eukaryotic expression system, and purified by Ni-affinity chromatography. After animal immunization, nine HA-specific monoclonal antibodies (mAbs), namely 5D5, 6B8, 9E7, 13F8, 14C3, 15F6, 16B5, 17H7, and 20C5, were generated. These mAbs specifically recognized HA protein in western blotting and indirect immunofluorescence assays (IFA). B-cell epitopes on HA were subsequently mapped using these mAbs by indirect enzyme-linked immunosorbent assay (ELISA), dot-blot, western blotting, and IFA. Six previously unreported linear B-cell epitopes were identified:
