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
Coccinia grandis is an interesting model system to understand dioecy in Cucurbitaceae family. Recent transcriptomics and proteomics studies carried out to understand the sex expression in C. grandis have resulted in identification of many candidate sex-biased genes. In absence of an efficient genetic transformation protocol for C. grandis, virus-induced gene silencing (VIGS) would be a powerful tool to enable gene functional analysis. In current study, we explored the apple latent spherical virus (ALSV) for gene knockdown in C. grandis. The viral infection was achieved through mechanical inoculation of ALSV-infected Chenopodium quinoa leaf extract onto the cotyledons of C. grandis. ALSV-VIGS mediated knockdown of CgPDS gene was successfully achieved in C. grandis by mechanical inoculation method resulting in characteristic photobleaching. Subsequently, we developed agroinfiltration compatible vectors for direct infection of C. grandis and shortened the time-frame by skipping viral propagation in C. quinoa. Typical yellow-leaf phenotype was observed in C. grandis plants agroinfiltrated with ALSV-CgSU constructs, indicating robust silencing of CgSU gene. In addition, we improved the infection efficiency of ALSV by co-infiltration of P19 viral silencing suppressor. These results suggest that ALSV-VIGS is suitable for characterization of gene function in dioecious C. grandis and it can help us understand the mechanism of sex expression.
