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

Yellow fever has been recently described in nonurban areas of Brazil despite 80 years of commercial vaccine use. Although the disease does not spread fear in the general population as it did in the past, yellow fever virus continues to cause many cases of severe disease. Persistence of the virus in the host is a new mechanism to be considered in the pathology of the disease. Immunization with a fractional dose of vaccine during emergency situations needs to be evaluated for antibody duration, and new and improved vaccines should be considered.
