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
We identified a novel nucleoplasm localized protein in Arabidopsis called AT-hook motif nuclear localized protein 1 (AHL1), which was isolated by visual screening of transformants using random GFP::cDNA fusions. AHL1 contains an AT-hook motif and unknown conserved PPC (plants and prokaryotes conserved) domain that includes a hydrophobic region. Approximately 30 paralogues were identified in the Arabidopsis genome. Proteins with PPC-like domains are found in Bacteria, Archaea and the plant kingdom, but in Bacteria and Archaea the PPC containing proteins of do not have an AT-hook motif. Thus, the PPC domain is evolutionary conserved and has a new function such as AT-rich DNA binding. AHL1 was mainly localized in the nucleoplasm, but little in the nucleolus and heterochromatic region, and was concentrated in the boundary region between euchromatin and heterochromatin. Biochemically, AHL1 was also found in the nuclear matrix fraction. In the M phase, AHL1 was localized on the chromosomal surface. The AT-hook motif was essential for matrix attachment region (MAR) binding, and the hydrophobic region of the PPC was indispensable for nuclear localization. Our results suggest that AHL1 is a novel plant MAR binding protein, which is related to the positioning of chromatin fibers in the nucleus by the presence of an AT-hook motif and PPC domain. In addition, AHL1 is located on the surface of chromosomes during mitosis.
