Neuroangiostrongyliasis Infection Risk Near Preschool Centres in Mallorca, Spain: A Pilot Micro-Epidemiological Study.

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
introductionNeuroangiostrongyliasis, caused by Angiostrongylus cantonensis , is a globally emerging zoonosis, with Spain being the only endemic country in Europe. Human infection occurs through ingestion of gastropods or paratenic hosts carrying third-stage larvae, often leading to eosinophilic meningoencephalitis. Alternative routes such as the ingestion of gastropod mucus or contaminated water have been proposed as potential routes of infection. Young children, particularly those under 5 years old, are at higher risk of neurological complications. This study aimed to assess the risk of neuroangiostrongyliasis transmission in preschool children at an endemic site in Mallorca through a micro-epidemiological approach.
methodsGastropods from an area where an infected rat was detected were identified and screened for A. cantonensis , with parasitic loads quantified via qPCR. Positive samples were digested to confirm the presence of L3. The distribution of infected gastropods was mapped and analysed for spatial clustering. Teacher surveys were conducted to assess exposure risks within the school.
resultsOverall prevalence in gastropods was 7.38%, with only slugs testing positive, showing a higher prevalence (28.2%). Milax nigricans, Deroceras reticulatum and D. panormitanum were confirmed as intermediate hosts, with D. panormitanum representing a new global host record. L3 larvae were observed in the three slug species. Larval loads ranged from 1 to 20,000 L3s. Infected slugs exhibited a clustered distribution near the positive rat location. Despite the limited epidemiological surveillance, teacher surveys revealed that children place gastropods in their mouths during outdoor activities.
conclusionsMultiple risk factors for neuroangiostrongyliasis were identified in an endemic area of Mallorca. Enhanced surveillance, improved diagnostics, treatment protocols and public health interventions are needed to prevent paediatric infections in Spain.
