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

Zoonotic anisakid nematodes commonly infect wild fish, and their presence in commercially caught species represents a consumer hazard due to risk of anisakidosis. The Greenland halibut (GLH) is a species of high commercial value to many countries, including Kalaallit Nunaat (Greenland), where GLH is the second most exported marine species. Despite this, the occurrence of anisakid nematodes in the flesh of GLH remains poorly studied. Additionally, the relationship between anisakid infection and 'Mushy halibut syndrome' (MHS), a condition affecting the fillet quality of GLH, has not been investigated. The aim of this study was to extend our knowledge of the occurrence of anisakid nematodes in GLH, with emphasis on fillet distribution, and explore associations with MHS. GLH (n = 104) from three offshore fishing grounds underwent necropsy and parasitological examination of the main fillet and belly flaps. Overall prevalence of third-stage larval infection was 44.2 %, while mean intensity and abundance were 4.6 and 1.3, respectively. When examining the fillets, third-stage larvae were predominantly found in the belly flaps. For a subsample of fish (n = 55), the investigation included parasitological examination of the body cavity and liver as well as extended necropsy, quality index method assessment and age estimation. The isolated third-stage larvae belonged to three species:
