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
The utilization of plant isolates as dyes in applied fields has gained considerable interest due to growing environmental concerns associated with the toxic synthetic dyes. In the present work, the agro-waste (such as grape leaves) has been valorized as a rich source of flavonoid-based natural dye for sustainable dyeing of woolen yarn. Microwave irradiation was further applied to dye molecules and wool yarn to enhance the dye uptake and process efficiency. Processing parameters for dyeing were optimized using Box-Behnken as a statistical design, and the results of the analysis revealed that the processing parameters, including temperature (80 °C), time (25 min), pH 5, and salt concentration (3 g/100 mL), significantly influence the color strength. The microwave irradiation of both flavonoid-based grape leaf extract and yarns up to 4 min, followed by dyeing, has given improved color yield up to a K/S value of 5.38. Metal mordants and bio-mordants were analyzed to improve dye fixation and sustainability. The pretreatment of yarn with Fe
