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

Chikungunya virus (CHIKV) caused more than 10,000 infections in Foshan, Guangdong, in 2025. Using plasma from acute-phase patients, we successfully isolated infectious CHIKV, confirmed by focus-forming assay and transmission electron microscopy. Whole-genome sequencing revealed that all isolates belonged to the ECSA-2 sub-lineage and were closely related to strains circulating on Réunion Island in 2024-2025, carrying adaptive mutations including C:T143A, E1:A226 V, and E2:I211 T/L210Q. Based on Foshan's 2025 population (∼9.6 million), the outbreak corresponded to a cumulative incidence of ∼104 cases per 100,000 inhabitants, highlighting intense transmission. Integrated virological, genomic, and epidemiological analyses characterize the rapid expansion of a single ECSA-2 genotype and underscore the need for strengthened arbovirus and genomic surveillance in southern China.
