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

Seasonal influenza vaccines are most frequently delivered as intramuscular inactivated vaccines, which elicit systemic responses against the immunodominant hemagglutinin (HA) head domain. An intranasally administered, live-attenuated influenza vaccine designed to stimulate mucosal immunity, FluMist, is the sole intranasal vaccine approved in the United States. However, FluMist has lower systemic immunogenicity and efficacy in adults compared with intramuscular formulations. In this study, human mucosal and systemic immunity were examined after seasonal intramuscular or intranasal vaccination. Nasopharyngeal swabs of adenoid tissue were used to longitudinally sample the upper airway. FluMist induced substantial increases in upper respiratory tract IgG
