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

Getah virus (GETV) has reemerged as an important mosquito-borne pathogen affecting livestock health in East and Southeast Asia. To quantify its epidemiological patterns, we conducted a Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA)-compliant meta-analysis of literature published between 2000 and September 2025. Analysis of 24 observational studies covering swine, equine, bovine, caprine, and wildlife populations using a random-effects model revealed a pooled mammalian seroprevalence of 26% (95% confidence interval [CI]: 0.17-0.38) and a pooled nucleic acid positivity rate of 2% (95% CI: 0.01-0.05), consistent with broad past exposure but limited detection of active viremia in cross-sectional surveys. Swine were identified as the main amplifying hosts, particularly in intensive farming regions of eastern and southern China, where herd seropositivity exceeded 60%. Results indicate a significant prevalence increase over the past 25 years. The established mosquito-swine-mosquito transmission cycle confirms GETV has transformed from a sporadic pathogen into a persistent threat within intensive farming environments.
