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
Two putative glycosyltransferases in Arabidopsis thaliana, designated reduced residual arabinose-1 and -2 (RRA1 and RRA2), are characterized at the molecular level. Both genes are classified in CAZy GT-family-77 and are phylogenetically related to putative glycosyltranferases of Chlamydomonas reinhardtii. The expression pattern of the two genes was analyzed by semi-quantitative RT-PCR using mRNA extracted from various organs of bolting Arabidopsis thaliana plants. In addition, promoter::gusA analysis of transgenic Arabidopsis thaliana containing a fusion between either the RRA-1 or -2 promoter fragment and the gusA reporter gene showed that whereas the RRA1 promoter was primarily active in the apical meristem, the expression pattern of the RRA2 promoter was more diverse but also highly active in the meristematic region. In addition, T-DNA mutant insertion lines of both RRA-1 and -2, were identified and characterized at the molecular and biochemical level. Monosaccharide compositional analyses of cell wall material isolated from the meristematic region showed a ca. 20% reduction in the arabinose content in the insoluble/undigested cell wall residue after enzymatic removal of xyloglucan and pectic polysaccharides. These data indicate that both RRA-1 and -2 play a role in the arabinosylation of cell wall component(s).
