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

Addressing the substantial yearly production of waste dredged slurry with high water content, it is imperative to adopt effective technical treatments for sustainable development. This paper establishes that the curing-flocculation-vacuum filtration (C-F-VF) method efficiently converts high-water content dredged slurry into back-fill soil, achieving rapid dewatering. The study delves into the mechanism facilitating swift dewatering and the heightened mechanical properties of the dewatered soil. The synergy of curing, flocculation, and vacuum filtration expedites the dewatering process. The pre-addition of a curing agent reduces the zeta potential of the slurry, enhancing its efficiency in subsequent flocculation and vacuum filtration. Although the curing agent experiences some loss during vacuum filtration, over 91.22% remains in the dewatered soil, fortifying its strength. Soil strength correlates with the water content post-vacuum filtration and the amount of cement added pre-filtration, with a proposed relevant strength prediction formula.
