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
Higher plants possess large multigene families encoding secreted class III peroxidase (Prx) proteins. In barley, two Prx cDNAs encoding HvPrx07 and HvPrx08 have been isolated and characterized to some extent with respect to a resistance-mediating function upon attack by the powdery-mildew fungus Blumeria graminis f.sp. hordei (Bgh). Here we present evidence for the tissue-specific accumulation of a new Prx mRNA, HvPrx40, in Bgh-attacked epidermis of barley (Hordeum vulgare). The encoded protein is predicted to be secreted into the apoplastic space of epidermal cells due to the absence of a C-terminal extension, which distinguishes it from other Prx proteins reported to accumulate in leaf epidermis. Transient overexpression of HvPrx40 enhanced the resistance of wheat (Triticum aestivum) and barley against Blumeria graminis f.sp. tritici (wheat powdery mildew) and Bgh, respectively. These findings were complemented by transient-induced gene silencing showing hypersusceptibility of barley leaf epidermal cells to Bgh. The local accumulation of oxidized 3,3-diaminobenzidine that reflects H2O2 production at sites of attempted fungal penetration was not reduced in HvPrx40-silenced cells, suggesting a role of this peroxidase other than the production of reactive oxygen species.
