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
This study was carried out to demonstrate the biotechnological potential of xylano-pectinolytic enzymes on scouring of ramie fibers. Optimization of bioscouring process showed a maximum effect of enzymes with 50-mM strength of buffer, pH 8.5, fibers to liquid ratio of 1 : 20 (g:ml). Xylanase and pectinase dosage of 7.5 and 3.0 IU, respectively, was found to be best for removal of xylan and pectin impurities, after treatment time of 1.5 h, at 50 °C temperature and 55 rpm agitation rate. EDTA and Tween 80 at concentration of 1.5 mM and 1.25 %, respectively, were found to be the best for effective removal of impurities, in order to improve hydrophilicity of the fibers. After bioscouring, brightness and whiteness values of bioscoured fibers were increased by 9.72 and 7.10% in comparison with control fibers. After enzymatic scouring, a reduction of 14.45 % in yellowness was also seen in ramie fibers. Enzymatic treatment resulted in 6.97% increased brightness, 10.64% increased whiteness, and 4.11% decreased yellowness as compared with scoured ramie fibers. The results indicated that scouring using xylanase and pectinase enzymes could be a substitute for chemical scouring technique. Enzymatic scouring is, therefore, environmentally sustainable and saves energy, also decreases the consumption of harmful chemicals used in alkaline scouring. This is the first report showing the effect of xylanase and pectinase enzymes, produced by a bacterial isolate, on physico-chemical and various optical properties of ramie fibers.
