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

Animal manure is considered to have great potential for phosphorus (P) recovery due to its high P content, while P recovery is limited by the transfer of P from the solid phase to the liquid phase. The conventional dissolution process by adding chemical acid reagents is not economically feasible for animal manure. This study used food waste (FW) as a co-substrate for the anaerobic fermentation of pig manure (PM) to achieve the release of P. The operational parameters were optimized, and the mechanisms of acidification and P release were further studied. The results showed FW promoted lactic acid production and rapid acidification. As FW increased from 0 to 80%, the concentrations of lactic acid rose from 0.12 ± 0.04 to 11.95 ± 1.37 g/L, with pH decreasing from 7.55 to 4.43. The ratio with FW/PM = 1:2 was the optimal condition, which led to the highest soluble phosphate concentration (350.39 ± 8.59 mg/L) in 72 h, with a TP release rate of 74.24 ± 1.81%. Multiple regression analyses established key relationships to predict pH changes in the reactor.
