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

Anaerobically pretreated composting leachate contains high ammonia load and soluble organic matter, which requires further treatment. In this study, simultaneous removal of COD, nitrogen, and phosphorus compounds from anaerobically pretreated composting leachate investigated by using an intermittent cycle moving bed airlift bioreactor (ICMBABR) supported by zeolite as a biofilm. The efficiency of COD, Total Kjeldahl Nitrogen (TKN), and phosphorous removal and contaminants profile during the process, and the mass balances were analyzed. A multilayer design used for the experimental design, and the effect of four variables including hydraulic retention times (4, 6, 8 h), the zeolite ratios (20, 35, 50%), the influent COD concentration (1, 2, and 3 g/L) and aeration duration (64, 73, and 82%) investigated by Response Surface Methodology (RSM). According to the results and process profile the sequence of anoxic and aerobic conditions, presence of the anaerobic zone in the bottom of the reactor, as well as the use of zeolite as adsorbent media, significantly allowed the simultaneous removal of COD (99%), TKN (95%), and total phosphorus compounds (90%) from anaerobically pretreated composting leachate and favorable potential to remove nitrogen compounds by high efficiency (79%) through simultaneous nitrification and denitrification (SND).
