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

We report the detection of yellow fever virus in Campinas and Ribeirao Preto city areas (two geographic areas within Sao Paulo State, Brazil) from September 2024 to February 2025. Phylogenetic analysis of six new genomes showed a re-introduction in 2022 from Midwest Brazil followed by persistence in Sao Paulo State. Continued surveillance in neotropical primates is required to prevent cases in humans.
