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
To facilitate prevention of clubroot disease, a major threat to the successful cultivation of Chinese cabbage (Brassica rapa L.), we bred clubroot-resistant (CR) cultivars by introducing resistance genes from CR turnips via conventional breeding. Among 11 CR loci found in B. rapa, we identified CRb in Chinese cabbage cultivar 'CR Shinki' as a single dominant gene for resistance against Plasmodiophora brassicae pathotype group 3, against which the stacking of Crr1 and Crr2 loci was not effective. However, the precise location and pathotype specificity of CRb have been controversial, because CRa and Rcr1 also map near this locus. Previously, our fine-mapping study revealed that CRb is located in a 140-kb genomic region on chromosome A03. Here, we determined the nucleotide sequence of an approximately 64-kb candidate region in the resistant line; this region contains six open reading frames (ORFs) similar to NB-LRR encoding genes that are predicted to occur in tandem with the same orientation. Among the six ORFs present, only four on the genome of the resistant line showed a strong DNA sequence identity with each other, and only one of those four could confer resistance to P. brassicae isolate No. 14 of the pathotype group 3. These results suggest that these genes evolved through recent gene duplication and uneven crossover events that could lead to the acquisition of clubroot resistance. The DNA sequence of the functional ORF was identical to that of the previously cloned CRa gene; thus, we showed that the independently identified CRb and CRa are one and the same clubroot-resistance gene.
