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

backgroundEchinococcosis remains highly endemic in some nomadic communities on the Qinghai-Tibet Plateau, China, where alveolar echinococcosis (AE) and cystic echinococcosis (CE) exhibit notably high prevalence rates of 3.64% and 2.37%, respectively. Recent settlement expansion in the region has raised concerns, as smaller, remote settlements often lacked waste disposal and sewage systems, potentially facilitating echinococcosis transmission. The aim of this study is to investigate how settlement characteristics influence echinococcosis transmission.

findingsThe study was conducted from 2022-2024 in nomadic communities of Shiqu County in China. The overall prevalence rate of echinococcosis in 51 settlements was found to be 2.34% (321/13,701; 95% CI: 2.10-2.61), which included a prevalence rate of 1.62% (222/13,701; 95% CI: 1.42-1.85) for AE and a prevalence rate of 0.72% (99/13,701; 95% CI: 0.59-0.88) for CE. The prevalence rate of AE was significantly (χ

conclusionsThis study indicates that the transmission of AE was more active than that of CE in the nomadic communities. Smaller, remote settlements had higher prevalence rates for both CE and AE. The density of owned dogs was a significant risk factor for CE prevalence but not for AE prevalence. Targeted interventions are needed in these high-risk settlements. Future research should investigate how settlement characteristics interact with hygiene practices, the infection status of intermediate and definitive hosts, and their population dynamics to better understand combined effects on echinococcosis prevalence.
