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
Hypocotyl segments of Arabidopsis (Arabidopsis thaliana) produce adventitious roots in response to exogenously supplied auxin. root primordium defective 1 (rpd1) is a temperature-sensitive mutant isolated on the basis of impairment in this phenomenon. This study describes further phenotypic analysis of the rpd1 mutant and isolation of the RPD1 gene. When adventitious root formation was induced from the rpd1 explants at the restrictive temperature, cell proliferation leading to root promordia formation was initiated at the same time as in wild-type explants. However, development of the root primordia was arrested thereafter in the mutant. Temperature-shift experiments indicated that RPD1 exerts its function before any visible sign of root primordium formation. The expression patterns of the auxin-responsive gene DR5:beta-glucuronidase and the cytodifferentiation marker gene SCARECROW suggest that the rpd1 mutation interferes with neither axis formation nor cellular patterning at the initial stage of root primordium development. Taken together with the effect of the rpd1 mutation on callus cell proliferation, these data imply a role for RPD1 in prearranging the maintenance of the active cell proliferation during root primordium development. Positional cloning of the RPD1 gene revealed that it encodes a member of a novel protein family specific to the plant kingdom. Disruption of the RPD1 gene by a T-DNA insertion caused embryogenesis arrest at the globular to transition stages. This phenotype is consistent with the hypothesized function of RPD1 in the maintenance of active cell proliferation.
