Genotoxicity of organic material extracted from particulate matter of alternative fuels.
Article in Environmental science and pollution research international, 2021. 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
Global demand for energy is rapidly increasing, and resources for the production of petroleum-based fuels are running out. For this, renewable fuels like biodiesel and hydrotreated vegetable oil biofuel are considered important alternatives to replace such fuels. In this study, we evaluated the in vitro genotoxicity effect on HepG2 cells of organic material extracted from particulate matter emissions of an engine fueled with conventional diesel or mixtures of diesel with 10% of biomass. The emissions were collected in two operational modes, 2410 rpm (slope simulation) and 1890 rpm (plane). Genotoxicity was evaluated through two methods, chromosomal aberration test and the alkaline comet assay. The former did not show any genotoxic effect, but the latter exhibited a statistically significant effect despite the operational mode of the engine and the concentration organic material extracted. In conclusion, regardless of the concentration of organic material extracted from particulate matter, the operational mode of the engine, or the fuel used, a significant damage of the DNA was found. In general, at the physicochemical level, a decrease in the amount of emissions of the used fuels is not directly related to a decrease in the genotoxicity potential.
