Not all West Nile virus lineages behave alike: dose-response differences between lineages 1 and 2.
Article in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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.
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
The globally distributed arbovirus West Nile virus (WNV) is expanding across Europe, with rising numbers of human cases and an increasingly broad geographic distribution. Transmitted primarily by Culex mosquitoes, WNV lineages 1 and 2 are pathogenic to humans, yet their differences in transmission dynamics remain unclear. As vertebrate hosts develop varying viremia, mosquitoes encounter a wide range of viral doses, which may influence transmission. Here, we investigated the dose-response differences between the lineages in Cx. pipiens biotype pipiens, Cx. torrentium, and Aedes albopictus. Mosquitoes were fed increasing titers of one strain of either WNV lineage, and infection and transmission were assessed after 14 days at 24 °C. Lineage 2 required lower infectious doses while causing higher transmission. Notably, Cx. torrentium was identified as a highly competent vector for lineage 2. These findings highlight important differences between WNV lineages, improve our understanding of dose-dependent transmission, and therefore support refined risk assessments in Europe.
