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 hydrogel carboxymethyl cellulose-polyvinyl alcohol-fumaric acid (CPF hydrogel) composed of Sodium Carboxymethyl Cellulose (CMC) and Polyvinyl Alcohol (PVA) with the ratio 3:1 and Fumaric Acid was synthesized through the wet chemical method and evaluated for the sorption of Zr (IV) ions from acidic leachate solution. The CPF hydrogel was characterized using FT-IR, SEM and EDX. The results confirmed its porous structure and surface functionality that promoted the effective metal ion sorption. Batch experiments were conducted to investigate the effects of contact time, initial concentration, V/m ratio, temperature, and pH on Zr (IV) extraction. Equilibrium was reached within 90 min at pH 1, V/m = 0.3, and 20 °C. The maximum sorption capacity was 239.7 mg g
