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
backgroundPhoretic mites and their carriers represent a dynamic system shaped by ecological and evolutionary processes. In highly specific phoresy, which involves long-term or permanent associations, profound consequences for phoretics, including cospeciation or the transition to phoretic parasitism, can occur. Mites within the complex of cryptic species of Uroobovella nova are carried exclusively on burying beetles (Nicrophorus spp.). Nevertheless, compared with the Poecilochirus mite-Nicrophorus system, this type of interaction remains poorly understood. In this study, we investigated whether different species of burying beetles play the same role in the local dispersal of U. nova deutonymphs. To achieve this, we compared the infestation patterns of deutonymphs among field-collected beetle species, while accounting for sex and body size.
resultsOur results revealed species-specific patterns in deutonymph infestations, with Nicrophorus vespillo being the most frequently infested species, followed by N. humator and N. interruptus. Furthermore, Nicrophorus vespillo and N. humator hosted the greatest number of deutonymphs, whereas in N. interruptus, the number of carried mites was significantly lower. The infestation pattern of U. nova demonstrated significant sexual bias, with males exhibiting higher mite prevalence and intensity than females. Interestingly, the variation in host body size was not a significant predictor of U. nova infestation. Although more mites were attached to the anterior than to the posterior parts of the beetle body in all the examined species, species- and sex-specific patterns in the distribution of deutonymphs were evident.
conclusionsSpecies-specific infestation patterns indicate that, at the local scale, individual burying beetle species play different roles in the dispersal of U. nova mites. Sex-specific infestation patterns suggest that biological differences between females and males may be key determinants of deutonymph infestations. Body size does not drive the prevalence, intensity, or distribution of deutonymphs. The assumption that larger hosts carry more symbionts does not hold universally in ecology.
