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
HSG1 (Heat shock-induced gene 1) is one of the high-temperature-induced proteins in grapevine. Sequence analysis has demonstrated that HSG1 is a grape Bcl-2-associated athanogene (BAG) that contains IQ and BAG domains in its sequence. HSG1 expression was not detected in leaves without heat treatment, while tendrils, stems, flowers, and berries expressed HSG1 even without heat treatment. By heat treatment at 45°C for 60 min, HSG1 expression was upregulated in both leaves and berries. HSG1-overexpressing Arabidopsis plant remained viable even after exposure to extremely high temperatures. Although no morphological changes were observed, the HSG1-overexpressing Arabidopsis plant exhibited faster floral transition than the control plant. Analysis of the transcription profile of HSG1-overexpressing seedling by cDNA microarray and quantitative RT-PCR demonstrated that the gene expression of the flowering promoter, CONSTANS (CO), in the photoperiod pathway was up-regulated in the seedling. Importantly, the overexpression of HSG1 increased CO expression by ~400% compared with the control seedling. Meanwhile, heat treatment upregulated grape CO expression in grape leaves. Our study provides the possibility that plant BAG protein may be related to the regulation of floral transition by activating CO expression in the photoperiod pathway.
