Does polyamine catabolism influence root development and xylem differentiation under stress conditions?
Article in Plant signaling & behavior, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
Amine oxidases (AOs) oxidize polyamines (PAs) to aldehydes, simultaneously producing the removed amine moiety and hydrogen peroxide (H2O2). AOs, which include copper-containing amine oxidases (CuAOs) and flavin-containing amine oxidases (PAOs), are stress-inducible enzymes involved in both PA homeostasis and H2O2 production. Here, we suggest that H2O2 derived from PAO-mediated PA catabolism has a role in inducing root xylem differentiation during plant stress responses, whereas its involvement in this event during plant development under physiological conditions is not suitably supported by the currently available data. Moreover, we show that spermidine (Spd) supply leads to a higher induction of cell death in wild-type (WT) tobacco (Nicotiana tabacum) plants as compared to tobacco plants over-expressing maize (Zea mays) PAO (S-ZmPAO) in the cell wall, in apparent contradiction with the already reported results obtained by the analysis of the corresponding WT and S-ZmPAO Spd-untreated plants. Considering this last observation, we propose that PAs diversely affect plant development and stress responses depending on the expression levels of AOs, which in turn may lead to different plant responses by altering the PAs/H2O2 balance.
