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 current study presents the synthesis and characterization of corn stalk fly ash (CSFA) based zeolites using a microwave-assisted hydrothermal technique for the removal of reactive blue 19 dye from wastewater. Fly ash derived from the corn stalk was observed to belong to class "F" having low moisture and carbon levels. CSFA and synthesized zeolites were characterized by X-ray diffraction spectroscopy (XRD), energy dispersive x-rays (EDX)-scanning electron microscopy (SEM), and fourier-transform infrared spectroscopy (FTIR). The synthesized zeolites were found to have a large surface area and pore size which are suited best parameters for a potential adsorbent. The adsorption ability of the raw fly ash and synthesized zeolites was studied in batch experiments by varying different parameters such pH, dye concentration, contact duration, and adsorbent dose. It was observed that a pH of 8, an adsorbent dose of 2.10 g/100 mL, and a contact period of 40 min were the optimum parameters for the removal of reactive blue 19 dye up to 98.7%. It can be concluded that CSFA based zeolites are efficient adsorbent for the removal of reactive blue 19 dye from wastewater and may be an inexpensive and environmentally viable alternative material for wastewater treatment.
