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
key messageProvide evidence that the Brassica B genome chromosome B3 carries blackleg resistance gene, and also the B genome chromosomes were inherited several generations along with B. napus chromosomes. Blackleg disease caused by fungus Leptosphaeria maculans causes significant yield losses in Brassica napus. Brassica carinata possesses excellent resistance to this disease. To introgress blackleg resistance, crosses between B. napus cv. Westar and B. carinata were done. The interspecific-hybrids were backcrossed twice to Westar and self-pollinated three times to produce BC2S3 families. Doubled haploid lines (DH1) were produced from one blackleg resistant family. SSR markers were used to study the association between B genome chromosome(s) and blackleg resistance. The entire B3 chromosome of B. carinata was associated with blackleg resistance in DH1. A second DH population (DH2) was produced from F1s of resistant DH1 lines crossed to blackleg susceptible B. napus cv. Polo where resistance was found to be associated with SSR markers from the middle to bottom of the B3 and top of the B8 chromosomes. The results demonstrated that the B3 chromosome carried gene(s) for blackleg resistance. Genomic in situ hybridization (GISH) and GISH-like analysis of the DH2 lines revealed that susceptible lines, in addition to B. napus chromosomes, possessed one pair of B genome chromosomes (2n = 40), while resistant lines had either one (2n = 40) or two pairs (2n = 42) of B chromosomes. The molecular and GISH data suggested that the B chromosome in the susceptible lines was B7, while it was difficult to confirm the identity of the B chromosomes in the resistant lines. Also, B chromosomes were found to be inherited over several generations along with B. napus chromosomes.
