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
backgroundAs an invasive species, Pomacea canaliculata exerts significant adverse effects on aquatic ecosystems. It can infect native freshwater snails, such as Cipangopaludina chinensis, by secreting pathogens, leading to increased stress and mortality. Gut microbiota play a crucial role in the survival and adaptation of gastropods, significantly influencing their health and resistance to environmental stressors. By comparing the gut microbiota composition and metabolic profiles between resistant (RE) and sensitive (SE) populations of C. chinensis, this study aims to elucidate the role of the gut microbiota in enhancing the survival of C. chinensis under the invasion pressure from P. canaliculata. And the mechanisms were further explored through gut microbiota transplantation, horizontal and vertical transmission experiments, and field studies. Video Abstract
resultsOur findings reveal that RE individuals exhibit greater gut microbiota diversity and a higher abundance of core microbiota, including Psychrobacter, Comamonas, and Pseudomonas, which are correlated with enhanced host survival in the presence of pathogen infections. Analysis of metabolite composition demonstrate that antibiotics and immunological enhancers are the main metabolites, which significantly enhance the host's resistance to pathogen infections. Notably, these core gut microbiota can be transmitted both horizontally and vertically, allowing C. chinensis populations to acquire resistance to the invasion of P. canaliculata. The SE group is enriched in pathogens, such as Mycoplasma. Following the transplantation of RE gut microbiota, SE individuals exhibited improved survival rates and core microbiota abundance. The vital role of core microbiota in maintaining the survival rate of C. chinensis was further confirmed in the field studies.
conclusionThis study highlights the crucial interactions between the gut microbiota and the host's adaptability, offering valuable insights for native species in response of invasive species pressure.
