A chickpea Kunitz trypsin inhibitor is located in cell wall of elongating seedling organs and vascular tissue.
Article in Planta, 2007. 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
Kunitz proteinase inhibitors in legumes have mainly been described as defence and storage proteins. Here, we report a Kunitz trypsin inhibitor, encoded by the CaTPI-1 gene from Cicer arietinum. The transcription of this gene mainly occurs in seedling vegetative organs, and is affected by the light and growth stages. The recombinant TPI-1 protein expressed in E. coli was seen to be an efficient inhibitor of trypsin. After the generation of polyclonal antibodies against recombinant TPI-1 protein, the protein was located in the cell wall of elongating epicotyls and radicles by Western-blot experiments, in agreement with the transcription pattern. These results, together with the fact that both CaTPI-1 mRNA and protein levels decreased with epicotyl growth, suggest a possible role in the elongation of seedling epicotyls and radicles. Immunolocalization analyses of the TPI-1 protein indicated that it is abundant in the cell walls of both immature primary xylem cells and surrounding parenchyma cells. This location has led us to explore potential functions for TPI-1 protein in vascular tissue during seedling elongation.
