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
Neolamarckia macrophylla is one of two species in genus Neolamarckia of the Rubiaceae family and distributed only in Indonesia. The two species possess several common properties, including fast-growing, superiority of stem form for wood industry and potential medicinal value. However, compared with N. cadamba that has been extensively explored for industrial and pharmacological applications, little is known about N. macrophylla. Here we sequenced the mitochondrial genome of N. macrophylla, which was 289,793 bp in length and assembled into a single circular structure. The genome contained 36 protein-coding genes (PCGs), 19 tRNA and 3 rRNA genes, and was characterized by a high AT content (55.03%), low coding-site per site (13.39%), typical C-to-U RNA editing, and codon usage bias. Homologous sequences accounted for 39.13% of its length in alignment with the nuclear genome of N. cadamba, and 1.2% in alignment with the chloroplast genome of N. macrophylla. A comparative analysis indicated that N. macrophylla substantially differed from N. cadamba, with an alternative conformation besides a smaller mitochondrial genome size, higher gene density per site, and less protein- and tRNA-coding genes. Strong purifying selection was present in all PCGs between the two species. Phylogenetic analysis revealed that the two species were divergent at about 6.757 Mya. This study provides the first complete mitochondrial genome sequence of N. macrophylla, enriching the genomic resource of the Neolamarckia genus for future study. The overall findings confirmed divergent structure of mitochondrial genomes between the two species in genus Neolamarckia.
