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 messageR2R3 MYB transcription factor GhMYB18 is involved in the defense response to cotton aphid by participating in the synthesis of salicylic acid and flavonoids. R2R3 MYB transcription factors (TFs) play crucial roles in plant growth and development as well as response to abiotic and biotic stresses. However, the mechanism of R2R3 MYB TFs in cotton response to aphid infestation remains largely unknown. Here, an R2R3 MYB transcription factor GhMYB18 was identified as a gene up-regulated from upland cotton (Gossypium hirsutum L.) under cotton aphid (Aphis gossypii Glover) infestation. GhMYB18, which has transcription activity, was localized mainly to nucleus and cell membranes. Transient overexpression of GhMYB18 in cotton activates salicylic acid (SA) and phenylpropane signaling pathways and promoted the synthesis of salicylic acid and flavonoids, which leads to enhancing the tolerance to cotton aphid feeding. In contrast, silencing of GhMYB18 increased the susceptibility of G. hirsutum to aphid. Additionally, GhMYB18 significantly promoted the activities of defense-related enzymes including catalase (CAT), peroxidase (POD), polyphenol oxidase (PPO) and phenylalanine ammonia-lyase (PAL). These results collectively suggest that GhMYB18 is involved in cotton defense response to cotton aphid attacks through regulating the synthesis of salicylic acid and flavonoids.
