Radiolabeling of Angiostrongylus vasorum- and Crenosoma striatum larvae: a novel method using PET/CT to unveil larval migration in the gastropod intermediate host (Lissachatina fulica).
Article in Parasites & vectors, 2025. 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
backgroundGastropod-borne metastrongyloid lungworm infections are poorly understood despite their importance in both veterinary and human medicine. This study intends to assess the use of nuclear imaging with whole-body positron emission tomography and computed tomography to scan radiolabeled Angiostrongylus vasorum- and Crenosoma striatum first-stage larvae (L1) while migrating in vivo in the obligate mollusc intermediate hosts. Here, the giant African snail (Lissachatina fulica) was used as a novel animal model for lungworm-associated investigations, as this gastropod species is known to act as a natural obligate intermediate host in the tropics for various metastrongyloid lungworms, including the zoonotic-relevant Angiostrongylus cantonensis. Radiolabeled A. vasorum- and C. striatum L1 migration was visualized through nuclear imaging after L1 oral infection or injection.
methodsLive L1 were collected through the standard Baermann funnel technique. After isolation and assessment of larval viability, collected A. vasorum- and C. striatum L1 were incubated with a radiolabeled glucose analogue,
