Evolution of Organic Components and Heavy Metals in Ceramics from Oil Sludge.
Article in ACS omega, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
Oil sludge (OS) is annually discharged with more than 300 million tons in the petroleum industry and is hardly utilized due to its inert properties and harmful components. Reusing it as raw materials to prepare ceramic materials has become a potential green and large-scale method. In this paper, OS mixed with oil sludge pyrolysis residue (OSPR) and oil sludge incineration fly ash (OSIFA) was converted into ceramics, and during the sintering process, the evolution of organic components and heavy metals in the ceramics was studied using X-ray diffraction (XRD), SEM-EDS, TG-FTIR, gas chromatography-mass spectrometry (GC-MS), thermodynamic analysis, physical property measurements, and heavy metal leaching tests. The results showed that the increasing proportion of OS was beneficial to reducing the initial densification temperature of ceramics and widening the range of sintering. The organic components in the OS mainly existed in the form of large carbon chain alkanes and esters of organic substances, and at 200-400 °C, organics burned to become CO
