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
The role of heterotrimeric G proteins in gibberellin (GA) induction of a-amylase gene expression was examined in wild oat aleurone protoplasts. Mas7, a cationic amphiphilic tetradecapeptide that stimulates GDP/GTP exchange by heterotrimeric G proteins, specifically induced alpha-amylase gene expression and enzyme secretion in a very similar manner to GA1. In addition, Mas7 stimulated expression of an alpha-Amy2/54:GUS promoter and reporter construct in transformed protoplasts. Both Mas7 and GA1 induction of alpha-amylase mRNA were insensitive to pertussis toxin. Hydrolysis-resistant nucleotides were introduced into aleurone protoplasts during transfection with reporter gene constructs. GDP-beta-S, which inhibits GDP/GTP exchange by heterotrimeric G proteins, completely prevented GA1 induction of alpha-Amy2/54:GUS expression, whereas GTP-gamma-S, which activates heterotrimeric G proteins, stimulated expression very slightly. Novel cDNA sequences from Galpha and Gbeta subunits were cloned from wild oat aleurone cells. By using RNA gel blot analysis, we found that the transcripts were expressed at a low level. Heterotrimeric G proteins have been implicated in several events during plant growth and development, and these data suggest that they may be involved in GA regulation of alpha-amylase gene expression in aleurone.
