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

The addition of zero-valent iron (ZVI) to the anaerobic digestion of food and kitchen waste (FKW) can significantly improve methane production efficiency. However, the impact of nano ZVI (nZVI) addition during both acidification and methanogenic phases of the two-phase anaerobic digestion of FKW remains unclear. This study investigated the effect of different nZVI particle sizes (50, 100, and 300 nm) introduced during the acidification phase on the overall performance of two-phase anaerobic digestion. The results revealed that nZVI improved the performance of the acidification phase. Particularly, 50 nm nZVI increased protein concentrations, likely owing to its toxicity, which caused microbial cell damage. The addition of 300 nm nZVI led to higher concentrations of soluble chemical oxygen demand (SCOD) and total volatile fatty acids (TVFAs), reaching 40,302.45 and 10,375.00 mg/L, respectively. In the methanogenic phase, 300 nm nZVI achieved the highest methane production, reaching 799.78 mL/g VS, which was enhanced by the optimal concentrations of TVFAs and Fe
