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
A functional contribution of pathogenesis-related 1 (PR-1) proteins to host defense has been established. However, systematic investigation of the PR-1 gene family in grapevine (Vitis spp.) has not been conducted previously. Through mining genomic databases, we identified 21 PR-1 genes from the Vitis vinifera genome. Polypeptides encoded by putative PR-1 genes had a signal sequence of about 25 residues and a mature protein of 10.9-29 kDa in size. PR-1 mature proteins contained a highly conserved six-cysteine motif and pI values ranging from 4.6 to 9. A major cluster with 14 PR-1 genes was mapped to a 280-kb region on chromosome 3. One particular PR-1 gene within the cluster encoding a basic-type isoform (pI 7.77), herein named VvPR1b1, was isolated from various genotypes of grapevine (Vitis spp.) for functional studies. Sequence analysis of PCR-amplified DNA revealed that all genotypes contained a single VvPR1b1 gene except for a broad-spectrum bacterial and fungal disease resistant Florida bunch grape hybrid, 'BN5-4', from which seven different homologues were identified. Duplication of VvPR1b1-related genes encoding acidic-type PR-1 isoforms was also observed among several genotypes. However, transgenic expression analysis of grapevine PR-1 genes under strong constitutive promoters in transgenic tobacco revealed that only the basic-type VvPR1b1 gene duplicated in 'BN5-4' was capable of conferring high level resistance to bacterial disease caused by Pseudomonas syringae pv. tabaci.
