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

Noroviruses are diverse positive-strand RNA viruses associated with acute gastroenteritis. Cross-reactive epitopes have been mapped primarily to conserved sequences in the capsid VP1 Shell (S) domain, and strain-specific epitopes to the highly variable Protruding (P) domain. In this work, we investigated a strain-specific linear epitope defined by MAb NV10 that was raised against prototype (Genogroup I.1) strain Norwalk virus (NV). Using peptide scanning and mutagenesis, the epitope was mapped to amino acids 21-32 (LVPEVNASDPLA) of the NV S domain, and its specificity was verified by epitope transfer and reactivity with a recombinant MAb NV10 single-chain variable fragment (scFv). Comparative structural modeling of the NV10 strain-specific and the broadly cross-reactive TV20 epitopes identified two internal non-overlapping sites in the NV shell, corresponding to variable and conserved amino acid sequences among strains, respectively. The S domain, like the P domain, contains strain-specific epitopes that contribute to the antigenic diversity among the noroviruses.
