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
Plant peroxidases are involved in numerous cellular processes in plant development and stress responses. Four plasma membrane-bound peroxidases have been identified and characterized in maize (Zea mays L.) roots. In the present study, maize seedlings were treated with different stresses and signal compounds, and a functional analysis of these membrane-bound class III peroxidases (pmPOX1, pmPOX2a, pmPOX2b, and pmPOX3) was carried out. Total guaiacol peroxidase activities from soluble and microsomal fractions of maize roots were compared and showed weak changes. By contrast, total plasma membrane and washed plasma membrane peroxidase activities, representing peripheral and integral membrane proteins, revealed strong changes after all of the stresses applied. A proteomic approach using 2D-PAGE analysis showed that pmPOX3 was the most abundant class III peroxidase at plasma membranes of control plants, followed by pmPOX2a >pmPOX2b >pmPOX1. The molecular mass (63 kDa) and the isoelectric point (9.5) of the pmPOX2a monomer were identified for the first time. The protein levels of all four enzymes changed in response to multiple stresses. While pmPOX2b was the only membrane peroxidase down-regulated by wounding, all four enzymes were differentially but strongly stimulated by methyl jasmonate, salicylic acid, and elicitors (Fusarium graminearum and Fusarium culmorum extracts, and chitosan) indicating their function in pathogen defence. Oxidative stress applied as H(2)O(2) treatment up-regulated pmPOX2b >pmPOX2a, while pmPOX3 was down-regulated. Treatment with the phosphatase inhibitor chantharidin resulted in distinct responses.
