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
backgroundCamellia huana, an endangered plant species with a high ornamental and medicinal value, is designated as a Class I protected plant in China. In the natural state, the flowers of C. huana have golden color and fragrance; however, our study group found that the outer layer of the petals of one C. huana plant was mutated and showed red color. Plant petals show a variety colors due to the synthesis and accumulation of pigments. However, thus far, few studies have investigated the formation and differences in flower color in C. huana. Carotenoids are the main color-forming components in C. huana flowers. C. huana petals also contain volatile compounds that impart a distinct fragrance to the flowers. In the present study, to better understand the regulatory mechanisms of carotenoids and volatile compounds in the petals of C. huana flowers of different colors, we used flowers obtained at different developmental periods of C. huana as the experimental materials and conducted metabolome and transcriptome analyses.
resultsThe results showed that C. huana is rich in volatile compounds. A total of 372 metabolites were detected in C. huana, which mainly included 72 terpenoids, 67 heterocyclic compounds, nitrogen-containing compounds, esters, aromatic hydrocarbons, 39 alcohols, and others; terpenoids, heterocyclic compounds, and esters were the predominant volatiles. Forty carotenoids were identified by carotenoid content analysis, and 10 genes were involved in carotenoid biosynthesis were screened for their significant differential expression, namely 15-cis-phytoene synthase (crtB), prolycopene isomerase (crtISO, crtH), beta-carotene 3-hydroxylase (crtZ), beta-carotene isomerase (DWARF27), 9-cis-beta-carotene 9',10'-cleaving dioxygenase (CCD7), zeaxanthin epoxidase (ZEP, ABA1), 9-cis-epoxycarotenoid dioxygenase (NCED), xanthoxin dehydrogenase (ABA2), abscisate beta-glucosyltransferase (AOG), and (+)-abscisic acid 8'-hydroxylase (CYP707A). A total of 12,089 differential genes were screened by transcriptome analysis.
conclusionsThe results of this study enriched the transcriptome data and provided new insights into the mechanisms of color and odor formation in the flowers of C. huana.
