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
Mitogen-activated protein kinase cascade plays a very important role in plant signal transduction mechanism. A full length cDNA of 1,514 bp length, corresponding to a mitogen-activated protein kinase gene was cloned from peanut (Arachis hypogaea). Based on its high homology with Arabidopsis AtMPK3, the cDNA was designated as AhMPK3. It carried an open reading frame of 1,113 bp encoding a 371 amino acid polypeptide. AhMPK3 bears TEY motif in its activation loop and belongs to the A1 subgroup of MAPK family. Southern blot analysis revealed that AhMPK3 exists in two copies in peanut genome and its structural organization revealed well-conserved nature of these signaling components across different species. AhMPK3 when transiently expressed in tobacco leaves was found to localize in both nucleus and cytoplasm. Transgenic tobacco plants ectopically expressing AhMPK3 exhibited enhanced resistance to first and second instar larvae of Spodoptera litura and constitutively higher transcript levels of defense response genes like PR1a, PR1b, LOX1, PI-II etc. Apart from this when wounded, transgenic plants accumulated high levels of PI-II and PR1b transcripts rapidly compared to wild type indicating the occurrence of a priming phenomenon.
