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
introductionGiven the need to identify parasites that may affect commercially important fish, and to contribute to knowledge of the parasitic fauna in Amazonian fish species, the main objective of this research was to study parasites from the gills of Brachyplatystoma tigrinum (Britski, 1981) (Siluriformes: Pimelodidae) what led to the discovery of a new species. MATERIAL AND
methodsFive B. tigrinum with 20–30 (25 cm) were collected in the section between Gran Perú, near the town of Tamishiyacu, in the Amazonas River (3°47′20.70″S 73°15′40.90″W), in Loreto, Peru. The collected fish were transported in boxes with ice to the laboratory for parasitological analyses.
resultsOne species of the Dactylogyridae was registered: Peruanella jorgepanduroi n. sp. The new species differs from its congener Peruanella madredediosensis Cruces, Santillán, Silvera, Morey, Rubin and Chero, 2024 by the termination of the MCO and the accessory piece, which in the new species have a pointed, almost straight termination, while in P. madredediosensis, both the MCO and the accessory piece bend forward; additionally, the presence of striations on the surface of the shaft and the point of anchors in P. madredediosensis is absent in the new species.
conclusionsThe results of this study constitute the second report of a dactylogyrid species parasitizing B. tigrinum, and at the same time, the second species of Peruanella Cruces, Santillán, Silvera, Morey, Rubin and Chero, 2024 described. This increases the knowledge of the biodiversity of monogenoids reported for Peru and the Neotropical region.
