Self-Induced Acidification of Fuel Ethanol and Its Role in Corrosion: Mitigation via Ion-Exchange Resins.
Article in ACS omega, 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
The presence of organic acids in fuel ethanol can significantly increase the corrosivity of automotive fuel systems. This study evaluated the relationship between ethanol composition and corrosion of stainless steel fuel injector valves and investigated the removal of acetic acid from fuel ethanol using ion-exchange resins. Long-term immersion assays (90 days at 70 °C) were performed and revealed no visible corrosion in anhydrous ethanol, while hydrated ethanol promoted severe corrosion accompanied by acetic acid concentrations exceeding 900 mg·L
