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
MicroRNA (miRNA)-mediated gene silencing is a master gene regulatory pathway in plant-pathogen interactions. The differential accumulation of miRNAs among plant varieties alters the expression of target genes, affecting plant defense responses and causing resistance differences among varieties. Botryosphaeria dothidea is an important phytopathogenic fungus of apple (Malus domestica). Malus hupehensis (Pamp.) Rehder, a wild apple species, is highly resistant, whereas the apple cultivar "Fuji" is highly susceptible. Here, we identified a 22-nt miRNA candidate named miRcand137 that compromises host resistance to B. dothidea infection and whose processing was affected by precursor sequence variation between M. hupehensis and "Fuji." miRcand137 guides the direct cleavage of and produced target-derived secondary siRNA against Ethylene response factor 14 (ERF14), a transcriptional activator of pathogenesis-related homologs that confers disease resistance to apple. We showed that miRcand137 acts as an inhibitor of apple immunity by compromising ERF14-mediated anti-fungal defense and revealed a negative association between miRcand137 expression and B. dothidea sensitivity in both resistant and susceptible apples. Furthermore, MIRCAND137 was transcriptionally activated by the invading fungi but not by the fungal elicitor, implying B. dothidea induced host miRcand137 as an infection strategy. We propose that the inefficient miRcand137 processing in M. hupehensis decreased pathogen-initiated miRcand137 accumulation, leading to higher resistance against B. dothidea.
