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
introductionLonicera caerulea L. (blue honeysuckle) is a noteworthy fleshy-fruited tree and a prominent medicinal plant, which possesses notable characteristics such as exceptional resilience to winter conditions and early maturation, and the richest source of functional anthocyanins, particularly cyanidin-3-glucoside. The molecular mechanisms responsible for its freezing tolerance and anthocyanin biosynthesis remain largely unknown.
objectivesHere, a chromosome-scale genome of L. caerulea was presented, aiming to examine the genetic foundations that underlie these characteristics of blue honeysuckle.
methodsThe PacBio HiFi reads and Hi-C data were used to construct high-quality genome of blue honeysuckle. Comparative genomic and transcriptomic analyses were conducted to elucidate the molecular mechanisms of freezing tolerance and anthocyanin biosynthesis.
resultsComparative genomics analysis between L. caerulea and L. japonica revealed that the dynamic changes of duplicated genes contributed to their phytochemical reconstruction and environmental adaptation. Moreover, the ABA and ICE-CBF-COR signaling pathways were closely correlated to the freezing tolerance of L. caerulea. Genome-wide identification and biochemical function indicated that three anthocyanin 3',5'-O-methyltransferases (LcOMT2, LcOMT14, and LcOMT20) and two 3'-O-glycosyltransferases (LcUGT78X1 and LcUGT95P1) were responsible for anthocyanin biosynthesis. In addition, LcUGT78X1 was regarded as the potent glycosyltransferase for the accumulation of cyanidin-3-glucoside in L. caerulea.
conclusionThis research elucidates the crucial roles of the ABA and ICE-CBF-COR signaling pathways in enhancing freezing tolerance, while also identifying highly efficient anthocyanin biosynthetic enzymes in L. caerulea. These findings advance the understanding of environmental adaptation and phytochemical production in Lonicera species.
