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 nucleocapsid (N) gene of equine arteritis virus (EAV) is highly conserved between isolates, and the N protein is an important antigen that induces immunity when horses are infected with EAV. This study describes the identification of a linear B-cell epitope on the N protein using the pepscan technique with a monoclonal antibody (mAb) 2B1 directed against the N protein. The N protein was divided into 11 overlapping peptides, each containing 16 amino acids associated with six overlapping amino acids. The fragments were expressed as MBP fusion proteins that were then used to probe the 2B1 mAb. The minimal epitope sequence was confirmed step-by-step using single amino acid residue deletion. One completely conserved linear epitope ((38)KPPAQP(43)) was identified that matched with EAV-positive serum in Western blots, thereby revealing the importance of these six amino acids of the epitope for antibody-epitope binding activity. This finding not only contributes to our understanding of the antigenic structure of the N protein of EAV but also has potential for the development of diagnostic techniques.
