Immunolocalization of two lignin O-methyltransferases in stems of alfalfa (Medicago sativa L.).
Article in Protoplasma, 1999. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Caffeic acid 3-O-methyltransferase (COMT) and caffeoyl CoA 3-O-methyltransferase (CCOMT) catalyze parallel reactions that are believed to be involved in the biosynthesis of lignin monomers. Antisera specific for alfalfa (Medicago sativa L.) COMT or CCOMT were raised against the enzymes expressed inEscherichia coli, and were used for immunolocalization studies in lignifying alfalfa stem tissue. Both COMT and CCOMT were localized to xylem parenchyma cells, as assessed by light microscopy and immunocytochemistry. Electron microscopy revealed that both enzymes were located in the cytoplasm of xylem parenchyma cells, and to a lesser extent, in the cytoplasm of phloem cells. There was no significant difference in the localization pattern of COMT and CCOMT, suggesting that the two enzymes may be part of a metabolic grid leading to production of lignin monomers in lignifying tissue of mature alfalfa stem internodes.
