1 · What the graph read from it

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.

2 · The registry

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

purposeThis study presents the first seroepidemiological investigation of anti-Kudoa spp. (Myxosporea: Multivalvulida) antibodies in the general population of the Canary Islands (Macaronesia, Spain), a region with high seafood consumption and pronounced geographic and climatic variability.

methodsA total of 1,096 serum samples from all seven islands were randomly selected and analyzed by ELISA for IgG and IgE antibodies against Kudoa spp. pseudocyst antigens extracted from locally consumed fish.

resultsThe overall seroprevalence for both IgG and IgE was 16.4%, indicating widespread exposure to Kudoa parasites. Marked geographic variation was observed: IgG seroprevalence was highest in Lanzarote (47%), Fuerteventura, and Gran Canaria (29.4%), while IgE prevalence peaked in La Gomera (63.3%), El Hierro (30.9%), and La Palma (27.4%). Sex-related differences were also detected, with higher IgE levels in males (p < 0.001). In addition, seropositivity varied by climate zone, with the dry desert zone showing the highest IgG prevalence (35.7%) and mild temperate zones the highest IgE prevalence (16.5%).

conclusionThese findings suggest that environmental, dietary, and behavioral factors strongly modulate host immune responses to fish-borne parasites. The results underscore the clinical and public health relevance of Kudoa spp., highlighting the need for ongoing surveillance and targeted preventive measures in populations with elevated seafood consumption. Overall, this research provides novel insights into the epidemiology, immune sensitization, and risk determinants of Kudoa exposure, contributing to improved management of seafood-borne zoonoses and evidence-based risk assessment for public health authorities.
