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
A new species of Pyrrhulina is described based on morphological and molecular evidence. Pyrrhulina punctata is distinguished from all congeners by the presence of a series of 7 to 16 irregular blotches of dark pigmentation on the flanks, equally marked in juveniles and adult specimens, the presence of 26-28 lateral-line scales, 17-21 maxillary teeth, 23-25 outer premaxillary teeth, 40-41 inner premaxillary teeth and 23 outer dentary teeth, the distinctly elongate rays on dorsal, pelvic and anal fin on adult males, the presence of irregular dark marks on the basal portion of anal-fin rays and intervening membranes, and the presence of a second dark blotch on the distal tip of longest dorsal-fin rays. The molecular data indicate a closer relationship with Pyrrhulina spilota, corroborating the morphological evidence and the shared colouration pattern. Besides the diagnostic characters allowing the recognition of both species, their distinction was corroborated by all species delimitation algorithms [Assemble Species by Automatic Partitioning (ASAP), Poisson Tree Processes (PTP) and Generalized Mixed Yule Coalescence (GMYC)] employed herein. In addition, the occurrence of P. spilota in the Madeira basin is refuted as the registers were based on misidentifications of Pyrrhulina vittata.
