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 paper, first, the effects of four polymers, including partially hydrolyzed polyacrylamide (HPAM), hydrophobically modified polyacrylamide (HMPAM), surface-active polymer (SAP), and heavy oil activator (HOA), on the stability of produced water were studied, and then, the effects of the four polymers on the performance of a nonionic polyether water clarifier AE411 were compared. The results of turbiscan stability index and heart-shaped structure microfluidic chip experiments showed that the four polymers can enhance the stability of oil droplets, ranked as SAP > HMPAM > HOA > HPAM. They can increase the absolute value of oil droplet ζ-potential, the elastic modulus of the oil-water interface, and the repulsion force between oil droplets. SAP and HMPAM significantly increased the absolute value of ζ-potential and the steric repulsion force between oil droplets, respectively, which enhanced the stability of oil droplets in produced water stronger than that of HPAM and HOA. The produced water treatment results presented that these polymers weakened the performance of AE411, and the weakening result was consistent with their impact on the stability of oil droplets. The four polymers would affect the adsorption of AE411 at the oil-water interface, thus affecting its performance of reducing the strength of the oil-water interface and generating attractive force on the oil droplets.
