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 small number of phytohormones dictate the pattern of plant form affecting fitness via reproductive architecture and the plant's ability to forage for light, water, and nutrients. Individual phytohormone contributions to plant architecture have been studied extensively, often following a single component of plant architecture, such as plant height or branching. Both brassinosteroid (BR) and gibberellin (GA) affect plant height, branching, and sexual organ development in maize (Zea mays). We identified the molecular basis of the nana plant2 (na2) phenotype as a loss-of-function mutation in one of the two maize paralogs of the Arabidopsis (Arabidopsis thaliana) BR biosynthetic gene DWARF1 (DWF1). These mutants accumulate the DWF1 substrate 24-methylenecholesterol and exhibit decreased levels of downstream BR metabolites. We utilized this mutant and known GA biosynthetic mutants to investigate the genetic interactions between BR and GA. Double mutants exhibited additivity for some phenotypes and epistasis for others with no unifying pattern, indicating that BR and GA interact to affect development but in a context-dependent manner. Similar results were observed in double mutant analyses using additional BR and GA biosynthetic mutant loci. Thus, the BR and GA interactions were neither locus nor allele specific. Exogenous application of GA3 to na2 and d5, a GA biosynthetic mutant, also resulted in a diverse pattern of growth responses, including BR-dependent GA responses. These findings demonstrate that BR and GA do not interact via a single inclusive pathway in maize but rather suggest that differential signal transduction and downstream responses are affected dependent upon the developmental context.
