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
backgroundThe root-knot nematode (RKN; Meloidogyne spp.) is the most destructive plant parasitic nematode known to date. RKN infections, especially those caused by Meloidogyne incognita, are one of the most serious diseases of tuberose. METHODS AND
resultsTo investigate the molecular mechanism in the host-pathogen interactions, the Illumina sequencing platform was employed to generate comparative transcriptome profiles of uninfected and Meloidogyne incognita-infected tuberose plants, during early, mid, and late infection stage. A total of 7.5 GB (49 million reads) and 9.3 GB (61 million reads) of high-quality data was generated for the control and infected samples, respectively. These reads were combined and assembled using the Trinity assembly program which clustered them into 1,25,060 unigenes. A total of 85,360 validated CDS were obtained from the combined transcriptome whereas 6,795 CDS and 7,778 CDS were found in the data for the control and infected samples, respectively. Gene ontology terms were assigned to 958 and 1,310 CDSs from the control and infected data, respectively. The KAAS pathway analysis revealed that 1,248 CDS in the control sample and 1,482 CDS in the infected sample were enriched with KEGG pathways. The major proportions of CDS were annotated for carbohydrate metabolism, signal transduction and translation related pathways in control and infected samples. Of the 8,289 CDS commonly expressed between the control and infected plants, 256 were significantly upregulated and 129 were significantly downregulated in the infected plants.
conclusionsCollectively, our results provide a comprehensive gene expression changes in tuberose during its association with RKNs and point to candidate genes that are involved in nematode stress signaling for further investigation. This is the first report addressing genes associated with M. incognita-tuberose interaction and the results have important implications for further characterization of RKN resistance genes in tuberose.
