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 messageBulk segregant analysis coupled with whole genome sequencing is a powerful approach and cost-effective method to identify loci controlling fruit traits in tomato. Domestication of fruit and vegetable crops was accompanied by selection for weight of the edible parts. Increases in fruit weight are controlled by multiple quantitative trait loci (QTL). To date, only two fruit weight genes have been cloned and a third has been fine-mapped. Genes that control locule number also impact fruit weight and two of them are known. To efficiently identify additional tomato fruit weight (FW) and locule number (LC) loci, six F2 populations were generated from crosses between closely related tomato accessions for which the alleles of the cloned FW and LC genes were known. We employed the bulk segregant approach coupled to whole genome sequencing (QTL-seq) which led to the identification of three highly significant and newly mapped FW QTL. fw11.2 was located in the distal part of chromosome 11 above the known loci fas and fw11.3; fw1.1 in the pericentromeric region of chromosome 1; and fw3.3 located ~1.6 Mb below the known fruit weight gene, SlKLUH/FW3.2. In addition, we mapped three LC QTL (lcn2.4, lcn5.1, and lcn6.1) although their significance was generally low. To confirm the location of the gene underlying fw11.2, we developed additional markers and conducted progeny tests. These results allowed us to narrow down the fw11.2 QTL to a region of ~750 kb corresponding to 66 candidate genes. Our research approach provided a cost-effective and time-efficient method for the identification of additional genes involved in FW and LC that could be used for both fruit development studies and crop improvement programs.
