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

Understanding the dissociation process in weakly charged polymer membranes is essential to design innovative charged polymer membranes with desirable transport properties for broader applications in sustainability. Previously, we designed a library of weakly charged polymer membranes, i.e., cross-linked acrylic acid (AA)-poly-(ethylene glycol) diacrylate (PEGDA) (AA-PEGDA) random copolymer networks with a wide ion-exchange capacity (IEC = 0-4 mequiv/g) range and limited water swelling. Here, we report the dissociation process of the weakly charged AA-PEGDA series in dilute (DI water) and concentrated (1 M NaCl (aq)) external salt solutions by probing dissociation in both 1) a solution phase (via potentiometric (POT) titration) and 2) a polymer phase (via ATR-FTIR analysis). Both POT titration and ATR-FTIR analysis describe the dissociation process well, showing similar dissociation parameters (degree of ionization (
