Isolation and characterization of a cDNA encoding a plant defensin-like protein from roots of Norway spruce.
Article in Plant molecular biology, 1996. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers.
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
We are studying the interaction between the roots of Norway spruce seedlings (Picea abies L. Karst) and a highly pathogenic isolate of Pythium dimorphum. Here, we report the isolation of a cDNA from spruce roots encoding a protein with high sequence similarity to plant defensins, designated as SPI1 (Spruce Pathogen Induced No.1). The transcript hybridizing to the SPII cDNA probe is highly induced in uninfected roots when the seedlings are transferred from solid to liquid incubating malt medium (hypoxic conditions). However, when the seedlings are transferred from solid to liquid malt media containing a saturating amount of P. dimorphum hyphae, the amount of transcript is unchanged the first day after infection, but then decreases on day 1, and is no longer detectable 2 days after infection. Since plant defensins may play a role in plant defence, their negative regulation upon infection might reflect a strategy employed by this pathogenic fungus to evade the effect of toxic gene products.
