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
Chinese cabbage (Brassica rapa subsp. pekinensis) is an economically important vegetable that has encountered four rounds of polyploidization. The fourth event, whole genome triplication (WGT), occurred after its divergence from Arabidopsis. Expansins (EXPs) are cell wall loosening proteins that participate in cell wall modification processes. In this study, the impacts of WGT on the B. rapa expansin (BrEXP) superfamily were evaluated. Whole genome screening of B. rapa identified 32 loci coding 53 expansin genes. Fifteen of the loci maintained a single gene copy, 15 maintained two gene copies and 2 maintained three gene copies. Six loci had no synteny to any Arabidopsis thaliana orthologs. Two loci were involved in tandem duplication. Segmental duplication and fragment recombination were dominant in accelerating BrEXP evolution. Three genes (BrEXPA7, BrEXLA1 and BrEXLA2) lost one of their ancestral introns, two genes (BrEXPA18 and BrEXPB6) gained new introns, and a domain tandem repeat (BrEXPA18) and domain recombination (Bra016981; not considered as expansin) were observed in one gene each. Further, domain deletion was observed in an additional five genes (Bra033068, Bra000142, Bra025800, Bra016473 and Bra004891, not considered as expansins) that lost one of their expansin-specific domains evolutionarily. These findings provide a basis for the evolution and modification of the BrEXP superfamily after a WGT event, which will help in determining the functional characteristics of BrEXPs.
