Performance and emission profiles of petroleum nut (
Article in Heliyon, 2024. 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
One of the traditional fuels for power generation in the Philippines is the petroleum diesel (PD). However, its extensive usage contributes to environmental degradation, health risks and climate change concerns. Alternative fuels such as petroleum nut biodiesel (PNB) may address the increasing consumption of PD amidst depleting fossil reserves and related issues. This study aimed to produce, characterize, and observe the behavior of PNB as a fuel in a compression ignition (CI) engine-power generation system at various loads of 0 %, 25 %, 50 %, 75 % and 100 %. Petroleum nut fruits were collected, extracted of oil then transesterified to produce PNB. The performance and emission profiles of the latter were determined. Degumming increased the PNB yield by 24.28 %. Additional refining decreased colorants and impurities. Majority of the chemical and physical properties of the PNB showed comparable values with those of PD. Various blends of PNB-PD were prepared and tested in terms of their performance and emissions. The 20 % PNB mixed with 80 % PD (B20) showed the most efficient performance after 100 % PD with at least 3.95 % decrease, whereas PNB for specific fuel consumption (SFC) showed at most 30.78 % higher than all fuels for all loads. The heat release rate (HRR) increases with increasing %PNB in the PNB-PD blend. PNB generally showed the highest CO
