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
BACKGROUND AND
objectivesSince postprandial lipid metabolism has emerged as a risk factor for cardiovascular disease, the quality of dietary fat may have a crucial role in atherogenesis and metabolic inflammation. In this study, we propose that the quality of dietary fats and the metabolic status of individuals modulate postprandial triglyceride-rich lipoprotein (TRL) composition and the response of macrophages to TRL.
methodsRandomized controlled crossover trial in the postprandial phase in 12 normal-weight adults and 12 adults with obesity. Each participant consumed both a Western-style (WB) and a Mediterranean-style (MB) breakfast in separate sessions, containing butter or olive oil as the fat source, respectively. Blood samples were collected at baseline (0 h), 2 h, and 4 h postprandially, and TRL were isolated and used to treat THP-1 macrophages.
resultsThe intake of the WB led to higher concentrations of inflammatory-related markers, particularly in individuals with obesity, and resulted in a higher content of saturated fatty acids and lower of monounsaturated fatty acids in TRL compared to the MB. Staining TRL-treated macrophages with Oil Red O revealed substantial lipid accumulation, which was more pronounced in cells cultured with 4 h TRL from individuals with obesity. This was also evidenced by upregulation of gene expression of lipoprotein uptake receptors following the consumption of the WB.
conclusionsConsumption of a WB led to a more pro-inflammatory postprandial profile and promoted greater lipid accumulation in macrophages, particularly in individuals with obesity, compared to a MB. These findings highlight the importance of fat quality in meals for cardiovascular risk management, especially in populations with obesity.
