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
The family Camallanidae includes nematodes traditionally classified based on the morphology of their buccal capsules. However, several questions have been raised about the validity of these characteristics for their classification. Despite having a remarkable diversity, our knowledge of camallanids in Brazil remains limited, leaving gaps in our understanding of the true species diversity in the country, their geographical distribution and host species associations. Therefore, this study presents a checklist of species in the family Camallanidae recorded in Brazil, including a review for the classificationa and new dichotomous key for identifying the genera. Camallanidae comprises 2 subfamilies with 13 valid genera, classified based on the morphology of the buccal capsule and trident, and on the presence, shape and distribution of internal ridges on the capsule. Thirty-seven species, distributed across 7 genera, have been recorded in Brazil so far, parasitizing 276 host taxa, including fish, chelonians and snakes, with no records of these nematodes parasitizing amphibians in the country. We reallocated five species of
