Phenolic Metabolism Explains Bitterness and Pungency of Extra Virgin Olive Oils.
Article in Foods (Basel, Switzerland), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Organoleptic features allow extra virgin olive oil (EVOO) to be distinguished from other commercial categories and to determine consumer preferences. In this study, we evaluated the influence of the phenolic content on the intensity of two characteristic attributes, namely, bitterness and pungency. The organoleptic analysis was carried out by a panel of trained tasters, who categorized a set of 200 EVOO samples produced in two consecutive crop seasons into three intensity levels ("Delicate", "Medium", and "Robust") according to current regulations. The total phenolic content was correlated with the intensity of both attributes, but a different contribution was identified for individual phenols. For bitterness, aglycone isomers of oleuropein and ligstroside provided over 70% discrimination power (estimated by receiver operating characteristic analysis), while oleocanthal and oleacein were associated with a decrease in bitterness intensity. In addition, the intensity of pungency intensity was related to the content of oleocanthal, oleomissional, and oleokoronal, as they allowed the classification of about 75% of the "Robust" pungency EVOOs. With these premises, it is possible to obtain olive oils with the desired intensity of bitterness and pungency by controlling the factors that influence phenolic metabolism.
