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
Perennial plants undergo a dormant period in addition to the growth and flowering phases that are commonly observed in annuals and perennials. Consequently, the regulation of these phase transitions in perennials is believed to be complicated. Previous studies have proposed that orthologs of FLOWERING LOCUS T (FT) regulate not only floral initiation but also dormancy. We, therefore, investigated the involvement of FT orthologs (GtFT1 and GtFT2) during the phase transitions of the herbaceous perennial gentian (Gentiana triflora). Analysis of seasonal fluctuations in the expression of these genes revealed that GtFT1 expression increased prior to budbreak and flowering, whereas GtFT2 expression was induced by chilling temperatures with the highest expression occurring when endodormancy was released. The expression of FT-related transcription factors, reportedly involved in flowering, also fluctuated during each phase transition. These results suggested the involvement of GtFT1 in budbreak and floral induction and GtFT2 in dormancy regulation, implying that the two gentian FT orthologs activated a different set of transcription factors. Gentian ft2 mutants generated by CRISPR/Cas9-mediated genome editing had a lower frequency of budbreak and budbreak delay in overwintering buds caused by an incomplete endodormancy release. Our results highlighted that the gentian orthologs of FRUITFULL (GtFUL) and SHORT VEGETATIVE PHASE-like 1 (GtSVP-L1) act downstream of GtFT2, probably to prevent untimely budbreak during ecodormancy. These results suggest that each gentian FT ortholog regulates a different phase transition by having variable responses to endogenous or environmental cues, leading to their ability to induce the expression of distinct downstream genes.
