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

Landfilled municipal solid waste (MSW) in developing countries generally produces a large amount of leachate due to high moisture content. The estimation of leachate production and level is of great importance to the capacity design of leachate treatment plants and the stability analysis of landfills. In this study, the leachate production ratios (the ratio of leachate mass to waste mass) in different countries and cities were first summarized to reveal the basic status of leachate generation. Then, a model was established to calculate the leachate production and level that considers the rainfall infiltration and the water released from MSW due to both primary and secondary compression (ignored in previous models). Finally, the proposed model was used in a case study of Laogang Landfill in Shanghai, China. It was found that the leachate proportion produced by compression was much higher compared with that produced by rainfall infiltration, ranging from 49 (rainy season) to 93% (dry season). The leachate released from waste due to secondary compression accounted for a high proportion (up to 25%) of the total leachate production, especially for aged MSW. The calculated leachate discharge amount and leachate level were close to the measured values because the possible low permeability layer at the bottom of the landfill was considered in this model.
