1 · What the graph read from it

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.

2 · The registry

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

In this study, a novel phosphate-functionalized hydrogel adsorbent, poly(acrylic acid-g-polyacrylamide) phosphate (PAA@PAm@P), was successfully synthesized for considerable adsorption of methylene blue (MB)-dye from aquatic solutions. The base hydrogel, poly(acrylic acid-g-polyacrylamide) (PAA@PAm), was prepared via free-radical copolymerization of acrylic acid and acrylamide, followed by mechanical homogenization to obtain hydrogel particles. Surface modification was subsequently achieved through phosphorylation using trisodium phosphate at 180 °C for 4.0 h, yielding the functionalized micron-sized PAA@PAm@P hydrogel. The fabricated materials were characterized using different analytical techniques, such as SEM, FTIR, TGA, and EDS, to confirm successful structural modification and functional groups incorporation. Batch adsorption experiments were conducted to investigate the influence of operational parameters including contact time, adsorbent dose, initial pH, initial MB-dye concentrations, NaCl concentrations, and temperature. The modified micron-sized PAA@PAm@P hydrogel exhibited rapid adsorption kinetics, reaching equilibrium within 15.0 min, which is twice as fast as the unmodified PAA@PAm (30.0 min). The material also demonstrated exceptional swelling behavior with a maximum swelling ratio of 5590% within 3 min, significantly higher than that of PAA@PAm (1712% after 7.0 min). Experimental results indicated that kinetic data were best described by pseudo-second-order (R
