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
Spirocamallanus rarus (Travassos, Artigas & Pereira, 1928) is reported for the first time parasitizing the intestine of Propimelodus eigenmanni (Van der Stigchel, 1946) collected from the Parauaú River, in Breves municipality, Pará, Brazil. Using light and scanning electron microscopy, several morphological aspects of this species were clarified and expanded upon. Newly described features include details of the cephalic structures, cuticular topography, the number and distribution of the caudal papillae in males, and the morphology of the vulva, anus and the phasmids on the tail in females. In this study, S. rarus was redescribed based on these new observations and a supplemental morphological re-study of the holotype and voucher specimens deposited in the Helminthological Collection of the Oswaldo Cruz Institute.
