Louse Flies on the Fly: Host Macroecology Shapes Interspecific Variation in Ectoparasite Prevalence Among Migrating Birds.
Article in Ecology and evolution, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 prevalence of ectoparasites is strongly affected by the host environment, which shapes not only host exposure, but also parasite transmission and survival. Louse flies (Diptera: Hippoboscidae) are obligate blood-feeding ectoparasites of birds and mammals, showing morphological adaptations to permanent life on the host body, such as dorsoventrally flattened bodies and strong claws. Here, we conducted a broad-scale screening of louse fly prevalence across 157 avian host species captured during autumn migration through Central Europe (over 100,000 individuals screened). We also ran a phylogenetically informed comparative analysis to identify host traits shaping interspecific variation in louse fly prevalence. We identified seven louse fly species across the entire sample, including two dominant species (
