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
Over the past two decades, molecular data have revealed a complex evolutionary history for the Neotropical felid genus Leopardus. A particularly problematic subset has been the L. tigrinus complex, which has been demonstrated to comprise more than one species. Recent molecular data indicated that it is not even monophyletic, comprising distinct Leopardus lineages with a similar morphology, which likely underlies the assumption that they formed a single species. To further investigate its composition and evolutionary history, we generated mtDNA data from multiple individuals sampled in Andean regions of Colombia and Peru. The Colombian samples formed a well-supported clade that was the sister-group of the Costa Rican lineage. Remarkably, the Peruvian L. tigrinus samples formed a different clade, placed at a distinct location within the Leopardus phylogeny, as a sister-group to (L. pardalis + L. wiedii). This unexpected result extends the inference of non-monophyly of the L. tigrinus complex, and raises the possibility that additional taxonomic entities may be contained in this genus.
