Chewing Lice From the Wings of Migrating Shorebirds: Diversity, Host Specificity, and Associations With Host Body Condition.
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
Ectoparasites may negatively affect their hosts throughout life, especially during breeding and other energetically demanding periods. In birds, feather-feeding ectoparasites may reduce host condition and performance during seasonal migrations. This study aimed to investigate the diversity of wing-collected chewing lice (Phthiraptera) and their associations with two groups of avian hosts, Charadriidae and Scolopacidae. We examined 1403 individuals from 20 migratory shorebird species to estimate louse prevalence and abundance, and a subsample of lice was identified using microscopic examination and DNA barcoding. In total, 26 lice species were identified across all hosts. Measures of louse prevalence and abundance varied widely among host species (9%-94% infested individuals and 0.2-26.4 lice per individual). Infestation differed significantly between age classes (higher in first-year than in adult birds) and between habitats used by birds during migration (higher at an artificial reservoir than in a natural river valley). Notably, louse abundance was negatively associated with condition (fat load and size-corrected body mass) in a time-constrained long-distance migrant, the wood sandpiper
