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
Ginger is an important spice crop with medicinal values and gingerols are the most abundant pungent polyphenols present in ginger, responsible for most of its pharmacological properties. The present study focuses on the molecular mechanism of gingerol biosynthesis in ginger using transcriptome analysis. Suppression Subtractive Hybridization (SSH) was done in leaf and rhizome tissues using high gingerol-producing ginger somaclone B3 as the tester and parent cultivar Maran as the driver and generated high-quality leaf and rhizome Expressed Sequence Tags (ESTs). The Blast2GO annotations of the ESTs revealed the involvement of leaf ESTs in secondary metabolite production, identifying the peroxisomal KAT2 gene (Leaf EST 9) for the high gingerol production in ginger. Rhizome ESTs mostly coded for DNA metabolic processes and differential genes for high gingerol production were not observed in rhizomes. In the qRT-PCR analysis, somaclone B3 had shown high chalcone synthase (CHS: rate-limiting gene in gingerol biosynthetic pathway) activity (0.54 fold) in the leaves of rhizome sprouts. The presence of a high gingerol gene in leaf ESTs and high expression of CHS in leaves presumed that the site of synthesis of gingerols in ginger is the leaves. A modified pathway for gingerol/polyketide backbone formation has been constructed explaining the involvement of KAT gene isoforms KAT2 and KAT5 in gingerol/flavonoid biosynthesis, specifically the KAT2 gene which is otherwise thought to be involved mainly in β-oxidation. The results of the present investigations have the potential of utilizing KAT/thiolase superfamily enzymes for protein/metabolic pathway engineering in ginger for large-scale production of gingerols.
