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

backgroundNoroviruses are a leading cause of acute gastroenteritis worldwide. Mucosal and cellular immune responses remain poorly understood, with most studies of noroviruses having focused on serological responses to infection.

methodsWe used saliva, feces, and peripheral blood mononuclear cells collected from persons who were administered Norwalk virus (NV) to characterize mucosal (salivary and fecal immunoglobulin A [IgA]) and cellular (NV-specific IgA and immunoglobulin G [IgG] antibody-secreting cells and total and NV-specific IgA and IgG memory B cells) immune responses following infection.

resultsPrechallenge levels of NV-specific salivary IgA and NV-specific memory IgG cells correlated with protection from gastroenteritis, whereas prechallenge levels of NV-specific fecal IgA correlated with a reduced viral load. Antibody-secreting cell responses were biased toward IgA, while memory B-cell responses were biased toward IgG. NV-specific memory B cells but not antibody-secreting cells persisted 180 days after infection.

conclusionsNV-specific salivary IgA and NV-specific memory IgG cells were identified as new correlates of protection against NV gastroenteritis. Understanding the relative importance of mucosal, cellular, and humoral immunity is important in developing vaccine strategies for norovirus disease prevention.
