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
The sacred ayahuasca brew, utilized by indigenous communities in the Amazon and syncretic religious groups in Brazil, primarily consists of a decoction of two plants: (i) the Amazonian liana known as Mariri or Jagube (Banisteriopsis caapi), and (ii) the shrub referred as Chacrona or Rainha (Psychotria viridis). While Chacrona leaves are rich in N,N-Dimethyltryptamine (DMT), a potent psychedelic, the macerated vine of Mariri provides beta-carboline alkaloids acting as monoamine oxidase inhibitors, preventing DMT's degradation. This study sequenced, assembled, and analyzed the complete genome of B. caapi's mitochondrion, yielding a circular structure spanning 503,502 bp. Although the mtDNA encompasses most plant mitochondrial genes, it lacks some ribosomal genes, presents some atypical genes, and contains plastid pseudogenes, suggesting gene transfer between organelles. The presence of a 7-Kb repetitive segment containing copies of the rrnL and trnfM genes suggests mitogenome isomerization, supporting the hypothesis of dynamic mitogenome maintenance in plants. Phylogenetics and phylogenomics across 24 Malpighiales confirms the sample's placement in the "Tucunacá" ethnovariety, aligning with morphological identification. This study spearheads efforts to decode the genome of this esteemed Malpighiaceae.
