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

Granular activated carbon (GAC) has been proved to accelerate the formation of aerobic granules during wastewater treatment. However, there has never been a study on the extracellular polymeric substances (EPS) or structural stability of the GAC aerobic granules. Thus, this study evaluated the impact of GAC on these characteristics. With GAC addition, granules matured 12 days earlier than those of the control group. Scanning electron microscopy showed the surface of aerobic granules enhanced by GAC to be denser and smoother than the surface of control granules, which could be the first line of defense against external selection pressure. After granules matured, there was no difference in contamination removal between the two types of granules. The protein content in EPS of GAC aerobic granules was higher than that of the control group; however, there was no difference in the polysaccharide content. EPS fluorescence in situ staining demonstrated that inside the aerobic granules, a high concentration of protein encapsulated the GAC. In addition, integrity coefficients indicated that GAC significantly improved the ability of aerobic granules to resist hydraulic shear. The result of hydrolase treatment proved that the outer layer structure of the GAC aerobic granules was maintained by β-polysaccharide, and the inner layer structure was maintained by protein. The ability of GAC-enhanced aerobic granules to resist single hydrolase was stronger than that of the control group.
