Viscosity of cooking oils affects dishwasher cleaning performance.
Article in Scientific reports, 2026. 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
Edible oil is a primary energy source in human diets. This study investigates the effects of heating temperature on the physicochemical properties of edible oils and their impact on dishwasher cleaning performance. First, the density and dynamic viscosity of peanut oil, rapeseed oil, and soybean oil were measured at room temperature and after heating to 50, 100, 150, 200, and 250 °C. Accordingly, two oils with the greatest viscosity difference-soybean oil at room temperature (SO_25) and peanut oil heated to 250 °C (PO_250)-were selected for dishwasher cleaning performance tests. Residue penalty score (RPS) and re-deposition penalty score (RDPS) were defined to characterize the cleaning ability and anti-redeposition performance of dishwashers. The results indicated that PO_250 generally exhibited lower cleaning scores. In the quick wash mode, the RPS and RDPS of PO_250 and SO_25 were relatively similar; however, in the standard wash mode, both RPS and RDPS of PO_250 were higher than those of SO_25. Statistical analysis further revealed that changes in washing mode have a greater impact on cleaning scores for high-viscosity oil than for low-viscosity oil. Moreover, low-viscosity oil exhibited greater inter-machine variability in dishwasher cleaning scores compared with high-viscosity oil. Scanning electron microscopy (SEM) imaging showed that PO_250 formed an oil film on the ceramic surface, whereas SO_25 appeared as discrete particles. This study provides a scientific basis for developing regionally applicable dishwasher testing standards, contributing to the optimization of cleaning technologies.
