Impact of Frying Olive Oil Type on the Physicochemical and Sensory Quality of Commercial Chicken Nuggets.

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
Frying is one of the most widely used cooking techniques, and olive oil is considered a suitable medium due to its high monounsaturated fatty acid content and natural antioxidants. Different olive oil categories vary in quality and price, yet their impact on fried food quality remains underexplored. This study used commercial chicken nuggets, a product commonly fried at home (180 °C), to evaluate how extra virgin, refined, and pomace olive oils influence nutritional (moisture, fat, and fatty acids), physicochemical (mechanical and acoustic properties, colour, and volatiles), and sensory attributes (Rate-All-That-Apply and hedonic tests). Overall, oil type produced minimal differences. Fat content did not vary (18.00-18.58 g/100 g), and although some fatty acid differences were significant, they were nutritionally negligible. Instrumental colour and most texture parameters were also unaffected. Volatile analysis showed terpenes as the most abundant class, with significantly higher levels in nuggets fried in extra virgin olive oil (344.8) compared with refined and pomace oils, which were similar (218.6 and 172.8, respectively). Nuggets fried in pomace olive oil were more often associated with toasted and burnt notes, supported by higher pyrazine levels (124.8 vs. 80.1 and 33.5), yet overall liking did not differ significantly (6.4 vs. 6.7 and 6.8). These results suggest that pomace olive oil, being considerably more affordable, represents a cost-effective frying alternative without compromising product quality.
